“The means to knowledge
i.e. our method of knowing (Pramāṇa – right perception), involves a progression,
a movement from Āgama (authentic teachings),
what we hear or perceive or learn from authoritative sources;
to Pratyakṣa (through the senses) to see the fire, itself, the fact, the truth, the reality.
Such a means to know is a movement from the gross to the subtle.
In Vikalpa, we don’t have this progression.”
– TKV Desikachar Madras December 19th 1988
