Self is everywhere,
shining forth from all beings,
vaster than the vast,
subtler than the most subtle,
unreachable,
yet nearer than breath,
than heartbeat.
Eye cannot see it,
ear cannot hear it nor tongue
utter it;
only in deep absorption can the mind,
grown pure and silent,
merge with the formless truth.
As son as you find it,
you are free;
you have found yourself;
you have solved the great riddle;
your heart forever is at peace.
Whole,
you enter the Whole.
Your personal self
returns to its radiant, intimate, deathless source.
Mandaka Upanishad
