Bhagavad Gita sings:

The really beneficial war is the conflict between matter and spirit,
for a single conquest in this war
results
in
domination of matter by the Self.
This is a conquest after which there is no possibility of defeat.

The Supreme Being is perceived
at the moment of attainment
and,
no sooner has this perception come about
then
the worshiper finds his own Soul blessed
with the attributes of God himself:

that his soul is-
like God-indestructible,
immortal,
eternal,
ineffable,
and universal.

Men who have given up all desire,
and whose actions are entirely free
from
the feelings of I and mine,
realize the ultimate peace
beyond which
there is nothing to strive for and achieve.

[Revered Swami Adgadanandji]

As expounded by most Revered Gurudev.
