“Since Dhyāna cannot occur without an object of concentration,
there must be an area (Deśa) where you fix your mind.
So, first you have to fix or bind (Bandha) your mind on a particular place (Deśa), a chosen object; this is known as (Deśa Bandha as in YS C3 v1).
And second, the mind should establish a relationship with this object which should last, at least, for a moment.”
TKV Desikachar Madras December 19th 1988

“Let us go into Siddhi, here the important word is Samādhi.
Unless we are born like that, then it’s a Siddhi, Samādhi is a Siddhi.
When we are in a state of absorption in something we are in Samādhi.
After which we appreciate the object in question and understand it more clearly.”
– TKV Desikachar France 1983
