²³¹⁶ According to the Yogabhāṣya on Y S. I 10 sleep is a special positive idea or experience (pratyaya) and not a mere absence of any activities or fluctuations of the mind, since when a man rises from sleep he reflects 'I have slept well, my mind is happy and makes my intellect clear' and this reflection on waking would not be possible if there had been no experience (during sleep) of the cause of such a feeling. Just as in *samādhi* one has to master other ideas (viz. misconception, fancy &c), so the Yogī has to master sleep also as a hindrance to the attainment of Samādhī.
