He loved her, protected her, and patiently taught her little by little. She kept those memories of care deep in her heart. To her, her father was both a gentle, honorable man and the strongest, bravest support in her life.<\/p>\n\n\n\n<p>On the day she graduated, her father arrived very early. During the ceremony, when he saw his daughter walk up to receive her diploma, his eyes filled with tears of pride. On the day she got married, at the wedding, he held the groom\u2019s hand and said in a low, trembling voice: Please take good care of my daughter. Don\u2019t let her cry. Don\u2019t let her come back to me in pain.<\/p>\n\n\n\n<p>Not long after that, her father passed away because of a serious illness.<\/p>\n\n\n\n<p>The pain came so suddenly that she lost her sense of direction. For many months, she barely ate, became very thin, stopped working, and had no energy to do anything. Every day, she just lay there, living in memories of the two of them, as if holding tightly to those memories could keep her father close.<\/p>\n\n\n\n<p>Before he passed away, her father did not leave her many things. There was only one watch\u2014a gift he had carefully saved up to buy for her because he thought it suited her. She did not wear it often, but she cherished it as the most precious thing in her life. After her father\u2019s death, it became even more valuable. She often kept it in her bag, as if carrying the watch meant carrying her father\u2019s presence with her.<\/p>\n\n\n\n<p>One day, on her way home, her bag was snatched.<\/p>\n\n\n\n<p>In that moment, she started shaking. It felt as if her whole world had collapsed. There were many important documents and valuable items in the bag, but she no longer cared about any of them. The only thought in her mind was: her father\u2019s watch was gone.<\/p>\n\n\n\n<p>In the past, she had once lost a watch worth tens of millions. At that time, she felt some regret over the money, and then it passed. But this time, even though the watch was only worth a few hundred thousand, the pain was so overwhelming that it took her breath away\u2014as if she had lost her father one more time.<\/p>\n\n\n\n<p><strong><em>At first glance, the girl\u2019s pain seemed to come from losing a watch.<\/em><\/strong><br>But in truth, the pain did not come from the watch itself. It came from the deep love she had for her father.<\/p>\n\n\n\n<p>The watch held special meaning for her because it was a gift her father left behind.\nShe clung to it as a way to soothe her longing, as proof that her father was still present beside her. When the watch was lost, that emotional support collapsed as well. The pain was no longer about losing an object, but about feeling as if she had lost her father once again.<\/p>\n\n\n\n<p>It was this attachment that caused the suffering to arise\u2014deep and intense, equal to the pain she felt on the day she said goodbye to her father forever.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Mo_hinh_cay_cua_kho_dau\"><\/span>The tree model of suffering<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1730\" height=\"2487\" src=\"https:\/\/linkachu.net\/wp-content\/uploads\/2026\/02\/z7502881256128_d8ffe1b273e5e44e717b5f4c78f37b18.jpg\" alt=\"S\u01a1 \u0111\u1ed3 c\u00e2y: g\u1ed1c r\u1ec5 c\u1ee7a kh\u1ed5\" class=\"wp-image-714\" srcset=\"https:\/\/linkachu.net\/wp-content\/uploads\/2026\/02\/z7502881256128_d8ffe1b273e5e44e717b5f4c78f37b18.jpg 1730w, https:\/\/linkachu.net\/wp-content\/uploads\/2026\/02\/z7502881256128_d8ffe1b273e5e44e717b5f4c78f37b18-209x300.jpg 209w, https:\/\/linkachu.net\/wp-content\/uploads\/2026\/02\/z7502881256128_d8ffe1b273e5e44e717b5f4c78f37b18-712x1024.jpg 712w, https:\/\/linkachu.net\/wp-content\/uploads\/2026\/02\/z7502881256128_d8ffe1b273e5e44e717b5f4c78f37b18-768x1104.jpg 768w, https:\/\/linkachu.net\/wp-content\/uploads\/2026\/02\/z7502881256128_d8ffe1b273e5e44e717b5f4c78f37b18-1068x1536.jpg 1068w, https:\/\/linkachu.net\/wp-content\/uploads\/2026\/02\/z7502881256128_d8ffe1b273e5e44e717b5f4c78f37b18-1425x2048.jpg 1425w, https:\/\/linkachu.net\/wp-content\/uploads\/2026\/02\/z7502881256128_d8ffe1b273e5e44e717b5f4c78f37b18-8x12.jpg 8w\" sizes=\"auto, (max-width: 1730px) 100vw, 1730px\" \/><\/figure>\n\n\n\n<p>From this tree diagram, we can see that clinging, attachment, and emotional bondage are the causes of suffering.\nAnd they also have their own roots.\nThe roots of the tree are what nourish and sustain all suffering.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Goc_re_cua_kho_dau_Tham_%E2%80%93_San_%E2%80%93_Si\"><\/span>The roots of suffering: Greed \u2013 Anger \u2013 Ignorance<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Tham_tham_lam_niu_keo\"><\/span>Greed (craving, clinging)<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>The girl was not only sad because she lost an object, but because she wanted to keep that keepsake forever, to hold on to the feeling that her father was still by her side.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><\/li>\n<\/ol>\n\n\n\n<p>Her love for her father was something truly beautiful. But when she could not accept the impermanence\u2014that her father could not stay with her for her whole life\u2014that love gradually lost its clarity (ignorance). She wanted her father to remain with her forever, regardless of the law of birth, aging, illness, and death that no one can escape.<\/p>\n\n\n\n<p>At this point, love transformed into craving.<br>Craving was not born from selfishness, but from clinging.<br>And when people try to hold on to something that cannot be held, suffering is inevitable.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"San_gian_du\"><\/span>Anger (hatred, resentment)<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>From her craving toward her father and the watch, when the watch was lost, she did not feel only sadness but also anger.\nFrom that very clinging, the mind of anger began to arise.<\/p>\n\n\n\n<ol start=\"2\" class=\"wp-block-list\">\n<li><\/li>\n<\/ol>\n\n\n\n<p>At the moment her bag was snatched away, she fell into a state of:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>shock<\/li>\n\n\n\n<li>trembling<\/li>\n\n\n\n<li>feeling as if the world had collapsed<\/li>\n<\/ul>\n\n\n\n<p>But this anger was not only anger toward the thief or frustration over losing her belongings.

So when the watch was lost, she felt as if her father had left her once again.<\/p>\n\n\n\n<p>But the truth is very simple:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The watch is just an object.<\/li>\n\n\n\n<li>Love and memories of her father do not exist inside that object.<\/li>\n<\/ul>\n\n\n\n<p>She suffered because she did not understand that everything is impermanent\u2014everything comes and goes in its own time. No one can stay with us forever, no matter how deeply we love them.<\/p>\n\n\n\n<p>This \u201cnot knowing\u201d prevented her from seeing the truth clearly.\nShe attached her longing and emotions to an external object. And when that object was lost, the suffering inside her erupted\u2014deep and intense.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Ao_tuong_tao_ra_Si\"><\/span>Illusions give rise to ignorance<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Illusion is like a layer of fog that covers the truth. The truth is still there, but because it is obscured, we can no longer see it clearly.<\/p>\n\n\n\n<p>The girl\u2019s illusion was the belief that:<br><strong><em>\u201cThe watch could preserve her father\u2019s image, keep the love, and hold on to the feeling that her father was still with her.\u201d<\/em><\/strong><\/p>\n\n\n\n<p>Because she believed this, when the watch was lost, she did not only lose an object\u2014she felt as if her emotions, memories, and attachment were taken away as well.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Cai_toi_%E2%80%93_Cua_toi_Phan_bon_manh_nhat_cua_kho_dau\"><\/span>\u201cI\u201d and \u201cMine\u201d: the strongest fertilizer of suffering<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>\u201cMy father\u2019s watch.\u201d<br>\u201cMy keepsake.\u201d<br>\u201cMy pain.\u201d<\/p>\n\n\n\n<p>Just by adding the word \u201cmy,\u201d everything immediately begins to operate in a different way. And because of that, suffering takes root even more deeply.<\/p>\n\n\n\n<p>If the lost watch had belonged to a stranger, the girl would not have suffered like this. If the watch had not been connected to her father, the pain would not have been so intense. In the same way, when we see someone else lose something, we may feel sympathy, but we do not feel the same sadness or anger as when we lose something ourselves.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Su_that_Chiec_riu_lam_do_cay_kho_dau\"><\/span>Truth: the axe that cuts down the tree of suffering<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Truth is like sunlight.\nWhen it appears, the fog of illusion naturally fades away. There is no need to chase it away or fight it\u2014where there is light, darkness has no place to remain.<\/p>\n\n\n\n<p>When people see the truth clearly, ignorance (misunderstanding, not knowing) gradually dissolves. And when ignorance is gone, suffering no longer has roots to cling to. Suffering does not disappear because we force ourselves to forget, but because we have understood.<\/p>\n\n\n\n<p>When the girl came to understand this, she still remembered her father and still loved him. But now, the memories of her father brought warmth and peace, not pain. She felt happy when thinking of him, because she knew that love does not disappear\u2014it simply no longer exists in its old form.<\/p>\n\n\n\n<p>understood that everything is impermanent.<br>understood that love does not exist in possession.<br>understood that nothing belongs to us forever.<\/p>\n\n\n\n<p>From this understanding, people awaken\u2014not to become cold or detached, but to live more lightly, to love more fully, and to be happier within their own lives.<\/p>\n\n\n\n<p><strong><em>Conclusion<\/em><\/strong><\/p>\n\n\n\n<p>The content above is my reflection and reinterpretation inspired by the book <strong><em>Right Livelihood (Kh\u1edfi Ch\u00e1nh Nghi\u1ec7p).<\/em><\/strong>This book looks at life and business through a Buddhist perspective.<\/p>\n\n\n\n\n\n<p>It is not a book to read just to \u201cgain more knowledge,\u201d but a book to help you <strong>understand yourself better<\/strong>understand why you suffer, and how to reduce suffering in a lasting way.
