“ For those who have conquered the mind, the mind is their friend. For those who have failed to do so, the mind acts like an enemy. ”
Source: Bhagavad Gita 6:6
Undoubtedly the mind is fickle and unruly; but by yoga practice and by dispassion, the mind may nevertheless be controlled.
One who has restrained the senses from their objects is firmly established in wisdom.
The best type of yogi is he who feels for others, whether in grief or pleasure, even as he feels for himself.
As a boat on the waters is carried off course by a gale, so an individual's discrimination is driven from its intended path when the mind succumbs to the wandering senses.
He who withdraws his senses from the objects of perception, just as a tortoise withdraws its limbs into its shell, is established in steady wisdom
