and Vedanta, each with its relative darsana, such as Nyaya, Yoga and Mimamsa.
The so-called Heterodox systems depend on intuitIve sources other than the Veda, but they are also capable of being classed under the broad triple heads, Realism (pluralism), Rationalism (dualism) and Intuitionism (integralism). Buddhism leads towards transcendental intuitionism; Jainism leans towards synthetic intuitionism; realising the relativism of the plural standpoints, whereas the tantras have always sought to bridge the gulfs between intuitions of several layers and levels of reality by the supreme activity of integration (carya) and doing (kriya).
The problem of man has been the conquest of misery; attainment of liberation, perfection, positive bliss and immortality have of course been other aims which have mingled with the first. The whole Darsana has to provide means to the attainment of goals of man (Parama purusarthas).
The question would be whether a new darsana is at all needed, since the other Darsanas are there to satisfy man's needs. It is clear that teachers of the Vedanta have all along taught that the four purusarthas of man have been satisfactorily gained through the pursuit of the Vedamarga. The paths of karma and jnana taught by them are said to help the attainment of both happiness here and in the hereafter. Beatitude is also had by following the path of the Veda and its upangas (subsidiaries).
The darsanas that have sprung out of the Vedas may be said to be the six systems - nyaya, vaisesika, samkhya, yoga and the two mimamsas. Though each one of them claims to be a whole exposition or system yet we can discern the emphasis made in respect of the world of Nature in the first two darsanas, the psychology of human being in the next two, whilst the last two darsanas deal with the transcendental reality that sustains, through works and through knowledge, the realities of nature and soul. Therefore the three modes of approach are clearly discernible - the adhi-bhautika, the adhyatmika and the adhi-daivika, and one is expected to study all the six systems (darsanas) in order to arrive at the Vedanta - the conclusive purport of the Veda. Other sciences have all helped to elucidate the Vedic Vision. Similarly the Puranas and the Itihasas have helped to explain and expatiate on the teachings of the Vedic Vision.
