Bhagavad gita
Chapter 5: Karma Sanyasa Yoga
(True Renunciation)
Krishna said:
22 The joy born of contacts have
Starting and end Oh Kawntheya!
It brings up pain only hence
The wise do not rejoice in them.
23Impulse born of lust or envy
Before released from own body
Who control it by strong will
That Yogi be the happiest man.
Krishna says that happiness that happened on by sensual contact, have a starting and hence they have an ending. Such happiness ultimately leads to pain. So the wise do not enjoy it. The man who restrain the feelings emerging from lust and envy; controls it before releasing it from the body; he is the real Yogi. He will be the happiest man, he will never be unhappy.
Let us also control our lust, envy and such negative thoughts through restrain. Then we all will be happy and then world will become wonderfully lovely.
