“The motive and state of mind of the teacher can
also vary and therefore produce varying results.
Thus the influence may or may not be for good,
depending on the person who is influencing and
the source of their powers; except in the case of Yoga,
because the actions of a Yogin are free of self–interest.
Thus, the motivation and intention of the teacher are
important in helping the student illuminate their Nimitta.”
– Paul Harvey on Yoga Sūtra Chapter Four verses 5-6

“Every action, even thoughts have some effect at some level.
Actions create fruits and leave seeds which eventually come
back to the performer of the action, either directly or indirectly.
These actions can be black, white, mixed, or have no colour.
The black actions can potentially have a negative comeback;
whereas white actions can potentially have a positive comeback.
But most actions are mixed, with a vague or indistinct outcome,
or they will have a distinct outcome, but it is difficult to discern.
Those actions that are seen as having no colour are the result
of actions from the highest dispassion, free of self–motivation.
Because these actions from a Yogin are free of self–motivation,
they are free of self–interest, either black, white or mixed.”
– Paul Harvey on Yoga Sūtra Chapter Four verse 7

“People often ask me if I teach Āsana.
When I say “Yes, I do.” they say,
“Oh you are a Haṭha Yogi.”
If I talk about the Yoga Sūtra
they say, “You are a Rāja Yogi.”
If I say I am chanting the Veda,
they say, “You are a Mantra Yogi.”
If I say I just practice Yoga,
they can’t understand.
They want to put a label on me.”
