Bhagavad Gita, Chapter 3 verse 38: As fire is covered by smoke, as a mirror by dust, as an embryo is enveloped by the amnion, so is the pure consciousness of Self covered by desire.
1) ‘As fire is covered by smoke.’ Desires arise from pure consciousness of Self and veil it.
2) ‘As a mirror is covered by dust.’ Outer attractive and aversive qualities found in objects of the senses (3.34) stimulate desires which in turn veil pure consciousness of Self (# 1).
3) ‘As an embryo envelops the amnion.’ The amnion nourishes the embryo. Powering the search for attractive and aversive qualities found in objects of the senses (# 2) desires nourish survival and evolution, and veil pure consciousness of Self (# 1).
How to free pure consciousness of Self from desires? Strengthen the mind through the practice of karma yoga (2.47, 3.08, 3.35): serve others' desires and innocently renounce your own. Experience pure consciousness of Self liberated from desires. Outsource desires to Nature (see final paragraph previous verse).
