“What is the nature of the Dṛśya or what can be perceived?
It has three qualities; it reveals, it acts, it has substance.
It has many components, the objects known and the means to know them.
They serve two roles.
When in strong association with the perceiver they produce pleasure or pain –
when this association is absent they let the perceiver visualise its own nature.
Experience of pleasure or pain is by the perceiver.
Freedom from them is also its fundamental situation.
This freedom is no different from Mukti.”
– T Krishnamacharya on Yoga Sūtra Chapter Two verse 18

“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

“The teacher decides which of the Tri Krama is the best for the student:
Śikṣaṇa Krama requires a perfect knowing to transmit a strict practice,
without any compromise, as it should be in Vedic chanting for example.
Rakṣaṇa Krama is aimed at protection and preservation;
it promotes continuity in any levels like health, abilities, knowledge, etc.
Cikitsā Krama looks for adaptation, healing, recovering…”
– TKV Desikachar speaking with his senior Western students London 1998
