focused on the 'I am' till it goes into oblivion, then the eternal
is, the Absolute is, Parabrahman is.
Putting aside everything, not allowing anything else to enter your
mind, in total earnestness remain with all the strength you have
focused on the 'I am'. Persist on this focus or meditation on the 'I
am' till you drive it away into oblivion. If your effort is sincere
and earnest enough the 'I am' is bound to disappear, for that is its
nemesis. Then whatever remains is your True being or Self, call it
Eternity, the Absolute or 'Parabrahman'.
