Dear Madam,
Sage Vasistha tells Rama - There are four gate-keepers at the entrance to
the realm of liberation or moksha. They are self-control, spirit of enquiry,
contentment and satsangh. The seeker should diligently cultivate the
friendship of these or at least one of them.
When the mind is at peace and the heart leaps to the Supreme Truth, when
all the disturbing thought-waves in the mind-stuff have subsided and there is unbroken flow of peace and the heart is filled with the Bliss of the Absolute,
when thus the Truth has been seen in the heart, then this very world
becomes an abode of bliss. ( YV )
Adi Sankara sums up all these in Bhaja Govindam . Is it not ?
According to Swami Ram Tirtha and swami Poornananda Tirtha , YV is the
greatest piece of literature in the world on Advaita Vedanta, unmatched
by any other in the world.
