What is this ras? To relish bliss is ras. It is the essence of happiness. The material ras can be divided into three categories. Tamasic (mode of ignorance) ras is highly destructive to the soul. It throws a person to the deep darkness. Rajasik (mode of passion) ras, though higher in experience than Tamasic, is also not at all satisfying to the soul. In fact it is very disturbing. Rajasik ras is like the itching sensation, the more you scratch more it comes back. Satvik (mode of goodness) ras is much higher than these two and is elevating to the soul but not yet liberating, it cannot satisfy the soul. Why? listen to get the answer.
