On foisting the bliss on to other things or happenings you are plunging into the Self, though unconsciously. If you do so consciously you call it Realisation.

Devotee:  Through poetry, music, japa, bhajan, beautiful landscapes, reading the lives of spiritual heroes, etc., one sometimes experiences a true sense of all-unity. Is that feeling of deep blissful quiet (wherein the personal self has no place) the “entering into the heart” whereof Bhagavan speaks? Will practice of that lead to a deeper samadhi, and so ultimately to a full vision of the Real?

Ramana Maharishi:  Again, there is happiness at agreeable sights, etc. It is the happiness inherent in the Self. That happiness is not alien and after. You are diving into the Pure Self on occasions which you consider pleasurable. That diving reveals the Self-existent Bliss.  But the association of ideas is responsible for foisting this bliss on to other things or happenings. In fact, it is within you. On these occasions you are plunging into the Self, though unconsciously. If you do so consciously you call it Realisation. I want you to dive consciously into the Self, i.e., into the Heart.
