Three directions, three destinies. Those established in sattva rise upward to higher realms. Those living in rajas stay in the middle, cycling through the human plane. Those sunk in tamas descend to lower states of being.
Drop three objects into water: a cork, a pebble, and a stone. The cork floats to the surface. The pebble hovers somewhere in the middle. The stone sinks to the bottom. Sattva is light like the cork and lifts the soul upward. Tamas is heavy like the stone and pulls it down. Rajas keeps the soul suspended in the middle — busy, striving, but neither rising nor falling.
The message here is not about cosmic rewards and punishments. It is about natural consequences. The quality of one's inner life determines the trajectory. Lightness rises. Heaviness sinks.
