Commentaries and Reflections

Commentary by T Krishnamacharya:

Mano Vikāra
Some actions I have done I have not got what I want.
Therefore this brings out certain changes
in certain mental processes and
a change in bodily activity.”

“Today this world is ‘standing’ on Vitarka
and it expands because of association.
It grows without any effort.
One has to put in special effort (Sādhana).
Otherwise nothing changes.”

Commentary by Paul Harvey:

Moha is a state of delusion, such as expressing
what is merely a self-opinion as if it is a reality.
Because expressing an opinion as if it’s a reality,
does not in fact actually mean that it will be true.
So how can we discern as to whether an opinion
that we experience as if a reality, is really true?”
