“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
