The whole evolution is one in its essence. The succession is the same, the sequences identical. Whether you are thinking of the unfolding of consciousness in the universe, or in the human race, or in the individual, you can study the laws of the whole, and in Yoga you learn to apply those same laws to your own consciousness rationally and definitely. All the laws are one, however different in their stage of manifestation.
If you look at Yoga in this light, then this Yoga, which seemed so alien and so far off, will begin to wear a familiar face, and come to you in a garb not wholly strange. As you study the unfolding of consciousness, and the corresponding evolution of form, it will not seem so strange that from man you should pass on to superman, transcending the barrier of humanity, and finding yourself in the region where divinity becomes more manifest.
