If you bring a yogic practice such as the Shambhavi Mahamudra into your life, the body will remain restful throughout the day, and your sleep quota will decrease.

When you experience the whole existence as part of you, when you can become pregnant with the whole creation - this is yoga.

This is a technology where without external input, you create a chemistry of blissfulness within you.

Your brain activity, your body chemistry, even your genetic makeup can be changed by practicing yoga.

If done properly, every asana is an energy process.
