6.28.22

yaṃ labdhvā cāparaṃ lābhaṃ manyate nādhikaṃ tataḥ |
yasminsthito na duḥkhena guruṇāpi vicālyate || 22 ||

nor one's who is addicted to too much sleep, nor one's who is always awake, devotion that is destructive of misery is his who is temperate in food and amusements, who duly exerts himself temperately in all his works, and who is temperate in sleep and vigils. When one's heart, properly restrained, is fixed on one's own self, then, indifferent to all objects of desire, he is one called a devotee. As a lamp in a windless spot doth not flicker, even that is the resemblance declared of a devotee whose heart hath been restrained and who applieth his self to abstraction. That (condition) in which the mind, restrained by practice of abstraction, taketh rest, in which beholding self by self, one is gratified within self; in which one experienceth that highest felicity which is beyond the (sphere of the) senses and which the understanding (only) can grasp, and fixed on which one never swerveth from the truth; acquiring which one regards no other acquisition greater than it, and abiding in which one is never moved by even the heaviest sorrow; that (Condition) should be known to be what is called devotion in which there is a severance of connection with pain. That devotion should be practised with perseverance and with an undesponding heart.
