“What is Samādhi?
It is the ability to experience the true nature of the objects of Meditation,
through a mind rid of the provocation of excitability and inactivity.”
– T Krishnamacharya’s commentary to Yoga Sūtra Chapter One verse 20

“These five Kleśa surround the heart of every individual.
They are related to the three Guṇa known as Sattva, Rajas and Tamas.
As long as one chooses not to inquire into the true nature of one’s self and acts mechanically,
they will unknowingly contribute to the dominance of the Kleśa.”
– T Krishnamacharya commentary on Yoga Sūtra Chapter Two verse 3

“When Kleśa are on  the move, time should not be lost.
Reflection is a must.
Reduction of all the factors that increase Rajas and Tamas,
including right food, company, study and Niyama is a must.
Without them, reflection leading to a reduction of the power of Kleśa will not work.”
– T Krishnamacharya commentary on Yoga Sūtra Chapter Two verse 11

“Sthira is the absence of Rajas.”
– TKV Desikachar commentary on Yoga Sūtra Chapter Two verse 46

‎”Use Samavṛtti in Prāṇāyāma to reduce the power of Rajas and Tamas.”
– T Krishnamacharya commentary on Bhagavad Gītā Chapter Five verse 27

“Its the combination (of Guṇa) thats important.
There is the simile of the oil lamp in the Sāṃkhya Kārikā Śloka 13.
The cotton wick – Light Property (Sattva)
The basin or bowl – Heavy Property (Tamas)
The oil – Flows this way or that (Rajas)
The moment you dip the cotton in the oil it takes on that property.
Thus the Guṇa work together to produce the flame.”
– TKV Desikachar Madras November 24th 1979 on Sāṃkhya and Yoga

“Lightness or Sattva is not always correct.
Sometimes it is necessary to create
heaviness and activity for memory, etc.”
– TKV Desikachar December 1st 1979

“There is an impression in some schools that Tamas and Rajas are to be rejected.
This is not so, both are necessary. It is the combination thats important.”
– TKV Desikachar December 1st 1979
