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 ॥
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.
तस्मात्त्वमिन्द्रियाण्यादौ नियम्य भरतर्षभ । पाप्मानं प्रजहि ह्येनं ज्ञानविज्ञाननाशनम् ॥
When your intellect ceases to be allured by the fruitive sections of the Vedas and remains steadfast in divine consciousness, you will then attain the state of perfect Yog.
नैनं छिन्दन्ति शस्त्राणि नैनं दहति पावकः। न चैनं क्लेदयन्त्यापो न शोषयति मारुतः ॥
the soul can never be Chopped by any or any kind of weapon, nor can it be burnt. Water cannot wet it nor can air dry it.
You have a right to perform your prescribed duties, but you are not entitled to the fruits of your actions. Never consider yourself to be the cause of the results of your activities, nor be attached to inaction.
While contemplating on the objects of the senses, one develops attachment to them. Attachment leads to desire, and from desire arises anger.
क्रोधाद्भवति संमोह : संमोहात्स्मृतिविभ्रमः । स्मृतिभ्रंशानुद्धिनाशो बुद्धिनाशात्प्रणश्यति
