Even consciousness is not unchangeable. It is a living, moving, growing and evolving process. It is impossible to know Reality through logic and science. It is known only in intuition which is a direct vision and experience transcending intellectual processes and scientific observations and reasonings. In intuition we comprehend the truth of things as a whole, as a complete process of the dynamic life of the spiritual consciousness.
Instinct is nearer to intuition than is intellect.
Intuition is instinct evolved, ennobled and become disinterested and self-conscious. Instinct, when not directed to action, but centred in knowledge, becomes intuition. Intuition has nothing of the mechanistic and static operations of the logical and the scientific intellect. Intellect is the action of consciousness on dead matter, and so it cannot enter the spirit of life. Any true philosophy should, therefore, energise and transform the conclusion of the intellect with the immediate apprehensions of intuition.
