The whole educative thrust of yoga
is to make things go right in our lives.
But we all know that an apple can appear perfect on the outside
but be eaten away by an invisible worm on the inside.
Yoga is not about appearances.
It is about finding and eradicating the worm,
so that the whole apple, from the skin inward,
can be perfect and a healthy one.
That is why yoga, and indeed all spiritual philosophies,
seem to harp on the negative -
grasping desires, weaknesses, faults, and imbalances.
They are trying to catch the worm
before it devours and corrupts the whole apple from the inside.
So yoga insists on examining, scientifically and without judgement,
what can go wrong, and why, and how to stop it.
It is organic farming of the self - for the Self.
-B. K. S. Iyengar
