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