“The first type of Pramāṇa, Pratyakṣa, arises from the continuous active link,
through the mind and senses, between Jīva and the object it perceives.
The second type, Anumāna, is when present perception is
based on what has been seen in other situations in the past.
For instance, when I see dark clouds, I think that it may rain.
With the third type, Āgamā, undistorted words from
a reliable source are the basis for perception.
The Veda are Pramāṇa by virtue of their source.
The sage Āpastamba proclaimed that the Veda are Pramāṇa for Dharma.”
– T Krishnamacharya on Yoga Sūtra Chapter One verse 7

“Vikalpa is a particular kind of Citta Vṛtti in which understanding
arises from the spoken word. Is this kind of understanding valid or not?
Patañjali, in the definitive Mahābhāṣya commentary on Saṃskṛta grammar,
states that the essence of the spoken word is not separate from the fact
or object it refers to. Objects themselves cannot express their various aspects;
only Śabda can present them to us. Śabda can convey nuances
of meaning that only a special faculty of the mind can grasp.
Such an ability to comprehend is not given to everyone.
The essence of this Sūtra is that Vikalpa is the mental activity by
which what is spoken is understood to mean what it represents,
even when the actual thing is not present.
Thus when we hear the word Sarpa we know it means snake
even though there is no snake present at the moment.”
– T Krishnamacharya on Yoga Sūtra Chapter One verse 9

“Imagination is knowledge
that comes from words
empty of substance.”
– Paul Harvey on Yoga Sūtra Chapter One verse 9

“In Sūtra 1.9 Patañjali defines Vikalpa as an
understanding arising from the spoken word.
How do we discern whether Vikalpa is actually what arises
from the spoken word from what was said to us, or what
arises from the spoken word in how what was said is heard?
In other words how to discern if there is any difference
between what is said to us and what we imagine we hear?”
– Paul Harvey on Yoga Sūtra Chapter One verse 9
