Mandukya Karika, verse 3.44
लये संबोधयेच्चित्तं विक्षिप्तं शमयेत्पुनः ।
सकषायं विजानीयात्समप्राप्तं न चालयेत् ॥ ४४ ॥
laye saṃbodhayeccittaṃ vikṣiptaṃ śamayetpunaḥ |
sakaṣāyaṃ vijānīyātsamaprāptaṃ na cālayet || 44 ||
44. If the mind becomes inactive in a state of oblivion awaken it again. If it is distracted,, bring it back to the state of tranquillity. (In the intermediary state) know the mind containing within it desires in potential form. If the mind has attained to the state of equilibrium, then do not disturb it again.
Shankara Bhashya (commentary)
When1 the mind is immersed in oblivion, i.e., in Suṣupti, then rouse it up by means of knowledge and by detachment. That is to say, turn the mind to the exercise of discrimination which leads to the knowledge of the Self. The word “Chitta” in the text bears the same meaning as “Manas” or mind. Bring2 the mind back to the state of tranquillity if it is distracted by the various objects of desires. When the mind is thus, by constant practice, awakened from the state of inactivity and also turned back from all objects, but not yet established in equilibrium,3 that is to say, when the mind still dwells in an intermediary state,—then know4 the mind to be possessed of attachment. Then the mind contains within it the seeds of desires for enjoyment and inactivity. From5 that state also, bring the mind, with care, to the realisation of equilibrium. Once the mind hás realised the state of equilibrium, that is, when it is on the way to realise that state, then do not disturb it again. In other words, do not turn it to (by attachment) external objects.
