Control the subtle forces
Yoga does not consist in sitting cross-legged for six hours or stopping the beatings of the heart or getting oneself buried underneath the ground for a week or a month…
Yoga is an exact science. It is a perfect, practical system of self-culture. It is the discipline of the mind, senses and the physical body. It helps the student to attain perfect concentration of the mind, ethical perfection, moral excellence and spiritual calmness. It is the master-key to unlock the realms of Peace and Bliss, Mystery and Miracle.
