“The Nature of the three Guṇa are Gratifying, Painful and Depressing,
(they serve) Brightness, Endeavour and Restraint,
and are mutually Supressing, Supporting, Producing, Co-existing, Mobile.”
– Sāṃkhya Kārikā of Īśvara Kṛṣṇa Śloka Twelve

“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

“Similarly, because of the proximity of Citta and Puruṣa,
what is the quality of one is taken to be of the other.
In our convention they are often taken as one
and not two distinct entities with different natures.
This state is Asmitā.”
– T Krishnamacharya’s commentary to Yoga Sūtra Chapter Two verse 6

“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

“Everything we see,
including the instrument of mind,
has three qualities or natures.
All matter has the three qualities.
In Saṃskṛta they are known as Guṇa.
In Sāṃkhya it is said that every problem
comes from the Guṇa and their interplay.
The effects can be based on what we see, eat, hear,
and the effects of what we see, eat, hear.
In Yoga one who has mastered themselves is one
who can produce whatever Guṇa is required.”
– TKV Desikachar on Sāṃkhya and Yoga

“One’s own actions can develop or make one Guṇa prominent.
Thus we can plan or practice Āsana or Prāṇāyāma to promote one Guṇa.
The practice of Yoga can influence the Guṇa.
the room where you practice can affect the Guṇa
by photographs, colour of paint, smell.
Even Mantra are classified into Guṇa.
This needs to be considered when using Mantra for the individual.
Meditation can be related to the Guṇa.
The object of our inquiry must be related or,
in accordance with what we want to produce.”
– TKV Desikachar on Sāṃkhya and Yoga

“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 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 on Sāṃkhya and Yoga

“Its the combination (of Guṇa) thats important.

“The Doṣa and the Guṇa are related,
we need to be able to understand the Guṇa
to be able to understand the Doṣa.”
– From study notes with TKV Desikachar England 1992

‘Āsana brings steadiness, health and lightness of limb.’
“For me, still to this day, one of the finest, simplest, direct and most succinct definitions on the purpose of Āsana within the processes and practices of Haṭha Yoga, is the definition offered in the Haṭha Yoga Pradīpikā Chapter 1 verse 17. It is a definition valid for any situation, or presentation, or as a response to questions from any background or level of interest around why we practice Āsana.
It can also be a springboard to discussing physiological qualities such as the relationship of Agni to the energetic qualities of health and lightness of limb. Or it can be a springboard to discussing psychological qualities such as the relationship of the Guṇa, Rajas, to mental qualities such as steadiness.”
