Arjuna: Tell me of those who live established in wisdom, ever aware of the Self, O Krishna. How do they talk? How sit? How move about? Lord Krishna: They live in wisdom who see themselves in all and all in them, who have renounced every selfish desire and sense craving tormenting the heart. Neither agitated by grief nor hankering after pleasure, they live free from lust and fear and anger. Established in meditation, they are truly wise. Fettered no more by selfish attachments, they are neither elated by good fortune nor depressed by bad. Such are the seers. Even as a tortoise draws in its limbs, the wise can draw in their senses at will. Aspirants abstain from sense pleasures, but they still crave for them. These cravings all disappear when they see the highest goal. Even of those who tread the path, the stormy senses can sweep off the mind. They live in wisdom who subdue their senses and keep their minds ever absorbed in Me.

(The Bhagavat Gita)
