Animals cannot have any high thoughts; nor can the Angels or Devas attain to direct freedom without human birth.

Anything that is secret and mysterious in this system of Yoga should be at once rejected. The best guide in life is strength. In spirituality, as in all other matters, discard everything that weakens you. Have nothing to do with it. Mystery-mongering weakens the human brain. It has well-nigh destroyed Yoga, one of the grandest of sciences

Through practice comes Yoga, through Yoga comes knowledge, through knowledge love, and through love bliss.

The chief helps in this liberation are Abhyasa and Vairagya. Vairagya is non - attachment to life, because it is the will to enjoy that brings all this bondage in its train; and Abhyasa is constant practice of any one of the Yogas.
