In spite of the sharp contrast in which the doctrine of Kapila stands to the system of the Vedanta, it works, in the last resort, with analogous factors, only it applies them differently. The soul and nature were put in the place of Brahman and Maya. Instead of the one intelligent principle, which the Vedanta establishes in the world-soul, Kapila maintains the plurality of individual spirits. In the Vedanta, it is true, nature exists as an illusion only: still it is a factor, which though it is also appearance, is nevertheless an existence, and in the last resort exists in Brahman; it has ever to be overcome anew, and thus in this system of unity, the basis is really a dualism. In the Sankhya doctrine nature is actually and materially existent; but the intelligent principle has to discover that this actually existent matter is, in truth, not existent for it, and cannot fetter the soul. If in the orthodox system the illusion of nature is to be annihilated by the free passage of the individual into Brahman, the doctrine of Kapila requires in the same way that man should rise to the idea that he is not nature, that the body is not his being, that he is not matter; it requires that man should be conscious of his freedom from nature, that he should return to his independence, in the same way as the Vedanta requires the absorption into Brahman. Then in the one case, as in the other, the individual escapes the restless movement of the world. In both systems the connection of the spirits and nature is only apparent, and the power of this deception in the spirit is removed by knowledge. Both proceed from the idea of an eternal being, self-contained, at rest, unmoved, self-sufficient; this the Vedanta ascribes to Brahman, while the Sankhya explains it as the nature of the soul. Nevertheless there is an important difference. In the Sankhya the intellectual principle is not the divine world-soul, which permits everything to emanate from itself and return to itself; it is the individual self, and besides this and material nature there is no real being, no real essence. If in the Vedanta liberation is the identification with the world-soul or the Godhead, liberation in the Sankhya is the retirement of the soul into itself. According to the Vedanta the liberated man says, I am Brahman; according to the Sankhya, I am not body nor nature.[381]
