Premanand Maharaj Ji
What is patience (dhairya) and how do I develop it?
Patience means not being shaken
Patience is not panicking when trouble comes, and staying steady when insult or criticism comes. It grows when you control the taste sense and the procreative sense and do bhajan.
If some calamity, insult, disrespect or criticism comes and we are not shaken, that will happen when we keep taste and the sensual urges under control and do bhajan of Bhagwan.
