Sometimes in order to practice surrender, and to be able to let go, we need to feel the support from something greater then us.
Here is an insight from the: Hanuman Chalisa
"Kumati nivara sumati ke sang"
Kumati means all negative tendencies of the mind. Nivara means to get rid of. To eliminate all illusions of the mind. Sumati ke Sangi means to give us bright intellect. Sri Hanuman gives us good thoughts and eliminates evil thoughts. These words can also mean that Sri Hanuman punishes people who are evil and he supports those who are good.
