Yoga -boby - mind connection

I learned a new dimension of Yoga in the book "integral healing "

what is yoga and How it helps us to connect  to sprituality is explained well in this book.

Yoga is not a regular exercise. It is much beyond. Yoga is for body -mind connection.

Additional new information to me is that  yoga beginner may fall ill due to insync body-mind progress. In that case it was advised to advance slowly.
