Attachment and aversion, likes and dislikes, are equally necessary for continued individual action. The Jiva eats what he likes and does not eat what he dislikes. He associates himself with certain objects, ideas and thoughts and shuns others. His likes and dislikes form the guiding principle of his actions. These affinities are called Râga and Dvesha by Patanjali and Mahâ Moha and Tamisra in the Purânas. The tenacious desire to live in the present body is called Abhinivesha by Patanjali. This desire becomes an instinct in the Jiva, so necessary is it for his preservation. The Purânas call it Andha-Tâmisra. Śridhara explains it as the shock we receive from a separation from all our present enjoyments. For, according to him, the idea of death is nothing but a sense of separation from our present enjoyments. These forms of Avidyâ were called into being that the forms of the previous Kalpa might be brought into existence, or that the work of creation might be undertaken. These faculties are the very essence of life manifestation. But the process has now been reversed. The work of creation is over. We have acquired the experiences of earth-life, and we are now destined to take a journey back to our home, the bosom of Íshvara, from which we all came. We have now to undo our sense of separateness. The five forms of Avidyâ are therefore called miseries (klesha) by Patanjali and he lays down rules for getting rid of them. After invoking Avidyâ, Brahmâ created the Kumâras, who were the most spiritual of the beings to be created. They were so spiritual, that they could not take any part in the work of creation. They had to bide their time, till there was spiritual ascent in the Universe. The Rudras, called the Blue-Red Kumâras, come next. Though highly spiritual themselves they did not object to take part in the work of creation. But as real factors in the work of dissolution, they were entirely out of place in the work of creation. We owe our idea of separateness or individuality to the Rudras. In the scale of universal life the agencies of dissolution carve out individual lives and their mission ends there.
