It is said, "mounam bhajaswa (pratice silence)". What is mounam
(silence)? It does not mean keeping the mouth shut. It
means, getting beyond the influence of all the senses and being
established always in the consciousness of One's own Reality.
When the mind withdraws from the external world, the tongue too
becomes silent. All senses follow suit. That is real
silence. Hence, you should learn to observe this world
from afar, with an uninterested attitude. Then, you can also
escape the wiles of the intellect which breeds doubts, delusions and
dualistic diversions, that draws you away from Bliss and Peace.
One who has reached that stage will be in highest peace and attain
the highest joy.
