Vasanas by Sri Swami Sivananda

Vasana (desire in subtle form) is a wave in the mind-lake. Its seat is the Karana Sarira. It exists there in the form of a seed and manifests in the mind-lake. Just as flowers are latent in seeds, Vasanas are latent in the Antahkarana and the Karana Sarira (seed-body). Daily new flowers blossom out. They fade out in a day or two. Similarly, Vasanas blossom out like flowers one by one, come out to the surface of the mind, generate Sankalpas in the mind of Jivas and goad them to strive to possess and enjoy the particular objects of enjoyment. Vasanas cause actions, and actions strengthen the Vasanas. This is a Chakra, vicious circle. On the advent of knowledge of Brahman, all Vasanas are fried out. The real enemies are the Vasanas within. Annihilate them. Eradicate them. They are inveterate.
