“Saṃkalpa is a serious intention between and both from teacher and student.
The less the depth of Saṃkalpa, the less the depth of what follows.
Once this is there what is required is Saṃskāra.
Saṃskāra is to remove the obstacles.
In a way it is Viyoga, so that certain things that get in the way are put aside.
Saṃskāra is like cleaning a vessel before you cook.
Saṃyoga is where something begins to happen.
The accumulation of what begins to happen between teacher and student is Saṃyoga.
Proportionate to the quality of the three, the output will be different”
– TKV Desikachar speaking with his senior Western students London 1998
