Question: What is the difference between pure Happiness, Peace and Bliss?
Swami Ramsukhdasji: By associating with divinity (chinmaitaah) i.e. in chanting etc. one derives pure happiness. When one does not become the enjoyer of pure happiness, one attains Peace. On not becoming the consumer or enjoyer of even Peace, one attains Bliss.
In pure happiness there are qualities, but Peace and Bliss are beyond qualities and attributes. By detaching from the world, one attains Peace, and by realizing Paramatma (God), one attains Bliss.
