1. Satvik or Pure happiness:
It arises from the elevation of the soul. But attaining this is not easy.
One has to practice a lot of discipline. That's why it feels like poison in the beginning but nectar in the end.
It is generated by the pure intellect that is situated in self-knowledge.”
This is the materialistic pleasure that is derived when the senses come in contact with external objects that create a feeling of gratification.
However, this kind of happiness is temporary.
Such happiness is like nectar at first but poison at the end.”
This is the lowest form of happiness and is derived from sleeping or being lazy.
The soul is never nurtured through these practices yet since there is a tiny sense of pleasure associated with it which is wrongfully considered a state of happiness
