Before replying the main issue " Desire", it would be in the fitness of things to give some relevant information. Among few others Karma, Attachment, Desire has been the focal theme of Geeta. Almost all copies of Geeta quote around dozen shlokas under the caption Geeta Mahatmya wherein we find a beautiful analogy of lead characters of Mahabharata . There is the mention of "Duryodhnavartani ".Duryodhan symbolized as intense whorl in a vast river current. Such whorl is powerful enough to capture and destroy anything in its ambit. It in fact implies a totally unstable and turbulent mind. Given this background, the desire of Duryodhan can never be worth accepting as an ideal role model, rather it needs to be shunned and decried. To pursue a desire as done by Duryodhan shall meet the same fate as met by Duryodhan. A lot has been discussed of desire in Geeta, ch 3
काम एष क्रोध एष रजोगुणसमुद्भव: ||
महाशनो महापाप्मा विद्ध्येनमिह वैरिणम् || 37||
The Supreme Lord said: It is lust alone, which is born of contact with the mode of passion, and later transformed into anger. Know this as the sinful, all-devouring enemy in the world.
धूमेनाव्रियते वह्निर्यथादर्शो मलेन च |
यथोल्बेनावृतो गर्भस्तथा तेनेदमावृतम् || 38||
Just as a fire is covered by smoke, a mirror is masked by dust, and an embryo is concealed by the womb, similarly one’s knowledge gets shrouded by desire.
आवृतं ज्ञानमेतेन ज्ञानिनो नित्यवैरिणा |
कामरूपेण कौन्तेय दुष्पूरेणानलेन च || 39||
The knowledge of even the most discerning gets covered by this perpetual enemy in the form of insatiable desire, which is never satisfied and burns like fire, O son of Kunti.
इन्द्रियाणि मनो बुद्धिरस्याधिष्ठानमुच्यते |
एतैर्विमोहयत्येष ज्ञानमावृत्य देहिनम् || 40||
The senses, mind, and intellect are said to be breeding grounds of desire. Through them, it clouds one’s knowledge and deludes the embodied soul.
तस्मात्त्वमिन्द्रियाण्यादौ नियम्य भरतर्षभ |
पाप्मानं प्रजहि ह्येनं ज्ञानविज्ञाननाशनम् || 41||
Therefore, O best of the Bharatas, in the very beginning bring the senses under control and slay this enemy called desire, which is the embodiment of sin and destroys knowledge and realization
इन्द्रियाणि पराण्याहुरिन्द्रियेभ्य: परं मन: |
मनसस्तु परा बुद्धिर्यो बुद्धे: परतस्तु स: || 42||
The senses are superior to the gross body, and superior to the senses is the mind. Beyond the mind is the intellect, and even beyond the intellect is the soul.
एवं बुद्धे: परं बुद्ध्वा संस्तभ्यात्मानमात्मना |
जहि शत्रुं महाबाहो कामरूपं दुरासदम् || 43||
Thus knowing the soul to be superior to the material intellect, O mighty armed Arjun, subdue the self (senses, mind, and intellect) by the self (strength of the soul), and kill this formidable enemy called lust.
and ch4-19, ch 5--23, 26 ch 7 --11. In ch 7 The Lord says to pursue such desires which is in accordance with the tenets of Dharma. Various teachers have explained Dharma as do's and dont's of karma as sanctioned by society in view of time, place, period and situation. I feel this may heip sum up the question relating to desire. With Regards, Hare Krishna.
