The highest form of grace is silence. It is also the highest spiritual instruction.All other modes of instruction are derived from silence and are therefore secondary. Silence is the primary form. If the guru is silent the seeker’s mind gets purified by itself. —Maharishi Ramana.
Comments; It is very clear that in silence we come to know our reality or self. According my experience when our mind has no objects it becomes self only, and we can enjoy self-realization.
Self realization is not a new thing which we have to buy from anywhere, it is always there, but we have to empty our minds by mediation or devotion. There is a gap between two thoughts. If we can make space between two thoughts you will be able to find bliss there. But no any word can explain it. After writing upnishidas Rishes said nati! nati! Meaning we described what we can but it is not a matter of language.
