There are many approaches - realism for example. Realism means to know, understand and interpret the world of Nature as a plural world comprising parts - infinitely divided and capable of being analysed (taken apart into pieces). It sees differences infecting and characterising all reality, sensory as well as rational analyses, and seeks to synthesise the plurality of elements and apprehend the principle of their unity.
There is the approach of idealism which postulates that all reality is mental or mind-dependent, if not mind-made. This may hold that all reality is a unity or One, but it can as well hold that it is a unity in multiplicity or a multiplicity in unity, both being mental. It may also hold that the multiplicity is derived from the One, or that the multiplicity is the appearance, real or illusory, of the one spirit or the Absolute. Idealisms range from romantic idealism to abstractionistic rationalism. In any case philosophers who uphold the reality of mind or Reason have invariably been idealistic.
There is another approach called the Mystical, which concludes that Reality is trans-rational and could only be grasped by transcendental intuition which is superior to the feeling of aesthetic individualism. Mysticism has, of course, infinite protean forms, but the main philosophical trend of mysticism lies in its intuitive grasp of reality as a whole, both in its single Oneness and in its infinite manyness in the One. It is trans-rational in the sense that the logic of mystic experience is not capable of being fitted into the neat dialectic schema of reason. Therefore, it appears at one end to be irrational and at the other end to be trans-rational, carrying a supreme con- viction or axiomatic reality or truth in its deliverances.
From sense to reason and from reason to intuition seems to be the levels of our passage to Reality.
Each of these approaches yields a Vision or Pattern and shape of Reality. Thus darsanas are framed. Indian thought presents the Reality in the three- fold way of Perception-dependent formulation of Reality (including super sensory perception), Reason-dependent formulation of Reality (as dualism), and Intuition-dependent formulation of Reality (as one in many, One is duality, One in its transcendent Oneness). They are Vaisesika, Samkhya,
