“Now let us go to some of his views on matters of interest. He believes that the only Yoga text that has any clear presentation of Yoga is the Yoga Sūtra.
But, he says, Rāja Yoga is just words without Sādhana, just like I read the other day, that philosophy itself is more interesting than any result from it.
However, with Sādhana, Rāja Yoga is the same as Bhakti Yoga.”
– TKV Desikachar from lectures on ‘The Yoga of T Krishnamacharya’,
given at Zinal, Switzerland 1981.

“Union of Jīva Ātman and Parama Ātman is a Siddhi not a Sādhana when it is felt or realised.
If this is clear then Rāja Yoga is a Siddhi.
However one has to work for it in Sādhana.
Anything that takes you in this direction is a Sādhana.”
– TKV Desikachar France 1983

“Haṭha Yoga is about Nāḍī Śodhana.
Rāja Yoga is about Citta Śodhana.”
