Dr. I. K. Taimni The Science of Yoga

According to the yogic philosophy it is possible to rise completely above the illusions and miseries of life and to gain infinite knowledge, bliss, and power through
enlightenment here and now while we are still living in the physical body.…No vague promise
of an uncertain postmortem happiness this, but a definite scientific assertion of a fact verified
by the experience of innumerable yogis, saints, and sages who have trodden the path of yoga
throughout the ages.”
