It is interesting that they have actualized the difference between nirodha variants in scope of classical Yoga; for instance the Sandilya Upanishad that in terms of significance I consider to be commensurate with the text of Yoga Sutras states that:
41. For the destruction [1] of the Chitta, there are two ways – Yoga and Jnana. O prince of sages, Yoga is the (forcible) repression of the modifications of the mind (vritti – A.S.) and Jnana is the thorough inquiry into them.
42-45. When the modifications of the mind are repressed, it (the mind (chitta – A.S.) verily obtains peace. Just as the action of the people cease with the stopping of the fluctuations of the sun (viz., with sunset), so when the fluctuations of the mind cease, this cycle of births and deads comes to an end. (Then) the fluctuations of Prana are prevented, when one has no longing from this mundane existence or when he has gratified his desires therein – through the study of religious books, the company of good men, indifference (to enjoyments), practice and Yoga or lond contemplation with intentness on any desired (higher) object or through practising one truth firmly.
The last shloka once again confirms the idea that I have expressed in my previous posts about the connection between chitta and prana.
[1] Of course the word ‘destruction’ is another translation defect. Now nirodha means destruction as well . But I draw the text in its standard translation.
