The Great Epic of the Bhārata dynasty 6.28.20

6.28.20

yatroparamate cittaṃ niruddhaṃ yogasevayā |
yatra caivātmanātmānaṃ paśyannātmani tuṣyati || 20 ||

When the mind, absolutely restrained by the practice of concentration, attains quietude, and when seeing the Self by the self, one is satisfied in his own Self; when he feels that infinite bliss—which is perceived by the (purified) intellect and which transcends the senses, and established wherein he never departs from his real state; and having obtained which, regards no other acquisition superior to that, and where established, he is not moved even by heavy sorrow;—let that be known as the state, called by the name of Yoga,—a state of severance from the contact of pain. This Yoga should be practised with perseverance, undisturbed by depression of heart.
