“In order to discipline the mind,
we need to develop a mental practice
that clearly reveals the distinction
between the nature of Jīva and Prakṛti.”
– T Krishnamacharya commentary on Yoga Sūtra Chapter One verse 12

“Abhyāsa is the practice of reflecting on the difference
between the nature of Jīva and the nature of Prakṛti,
which brings momentary tranquillity to the mind and
eventually leads to complete and sustained mental tranquillity.”
– T Krishnamacharya’s commentary to Yoga Sūtra Chapter One verse 13

“In the second and third Sūtra the means to realise Samādhi
and the true nature of Jīva were explained.
The term used in those Sūtra is Draṣṭṛ
– that which perceives and aids in perception.”
– T Krishnamacharya’s commentary to Yoga Sūtra Chapter One verse 23

“It is through Praṇavo Japam that
the true nature of the Jīva is realised.”
– T Krishnamacharya’s commentary to
Yoga Sūtra Chapter One verse 29

“Serious practitioners of Yoga from Vedic times to the present day
emphasise that a clear mind is a prerequisite for Bhakti and
that it is only through Bhakti that the true nature of the Jīva is revealed.
Bhakti, singe minded and abiding, is the mark of a certain unique relationship
characterised by unshakeable faith, absolute trust and boundless devotion.”
– T Krishnamacharya commentary on Yoga Sūtra Chapter One verse 30

“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
