यथा दीपो निवातस्थो नेङ्गते सोपमा स्मृता ।
योगिनो यतचित्तस्य युञ्जतो योगमात्मनः ।। ६.१९ ।।

Profundity of the Self-state

The mind resting upon the Self is such a comprehensive and ultimate spiritual state that it leaves nothing more to be sought or gained. Krishna explains how full such an inward steadiness and restfulness is:

Just as a lamp placed in a windless place, has an unflickering flame, the disciplined mind of a yogi remains firm, still and poised.

This statement is immensely profound to be treated casually. The life in the world, given as it is to a variety of activities, always destabilizes the mind, making it desultory and distracted. If this plight is to be redressed, the pursuit of yoga is the only means.
