“People come to study Yoga for many reasons,
however it comes into two groups.
1. They come to learn or study (Śikṣaṇa).
2. They come to us for support rather than to study (Rakṣaṇa).
So the Yoga we offer to the person who is inquiring
is not the Yoga we offer to the person seeking protection.
Therefore one can give the wrong advice (Asat viniyoga) to the right person
and vice versa (Asat viniyoga).
This can do more harm than if the person had not come.
The intention must be right as must be the execution.”
