How to overcome passions - Sri Ramana Maharshi

Devotee: How shall I overcome my passions?

Maharshi: Find their root, and then it will be easy.
(Later) What are the passions? Kama (lust),
krodha (anger), etc. Why do they arise?
Because of likes and dislikes toward the
objects seen. How do the objects
project themselves in your view? Because of
your avidya, i.e., ignorance. Ignorance of
what? Of the Self. Thus, if you find the Self
and abide therein, there will be no trouble
owing to the passions.
(Later) Again, what is the cause of the
passions? Desire to be happy or enjoy
pleasure. Why does the desire for
happiness arise? Because your nature is happi-
ness, itself, and it is natural that you come into
your own. This happiness id not found any-
where besides the Self. Do not look for it else-
where, but seek the Self and abide therein.
Still again, that happiness which is natural is
simply rediscovered, so it cannot be lost.
Whereas the happiness arising from other
objects is external and thus liable to be lost.
Therefore, it cannot be permanent, and so it is
not worth seeking
