Dhamma Happiness vs Worldly Happiness - Ajahn Dhammasiha
There are two different kinds of happiness, worldly of connected with Dhamma. We can experiencewordly pleasant feeling based on sensual indulgence, or based on acquiring material possessions. However, this coarse wordly happiness is often accompanied with negative side effects, one has to increase dosage to get the same 'kick' again, and in any case it's very impermanent.
On the other hand, we can experience a superior, more sublime happiness based on Dhamma, e.g. the joy of generosity, the clear conscience from keeping precepts, the ease resulting from sense restraint, and the bliss of samādhi and insight. This Dhamma happiness is not dependent on anything external, we will take it with us even beyond death to the next life, and ultimately it will lead us to the supreme happiness of Nibbāna.
