Blavatsky writes that “everyone of us possesses the faculty, the interior sense, known as intuition, but how rare are those who know how to develop it! It is, however, the only faculty by means of which men and things are seen in their true colors.
It is an instinct of the soul, which grows in us in proportion to the use we make of it, and which helps us to perceive and understand real and absolute facts with far more certainty than can the simple use of our senses and the exercise of our reason. What are called good sense and logic enable us to see the appearance of things, that which is evident to everyone.
The instinct is a projection of our perceptive consciousness, a projection which acts from the subjective to the objective, and not vice versa, awakens the spiritual senses in us and the power to act; these senses assimilate to themselves the essence of the object or of the action under examination, and represent them to us as they really are, not as they appear to our physical senses and to our cold reason.”
In the words of Professor A. Wilder:
We begin with instinct, we end with omniscience
(Theosophy Vol 8)
