Meditate like Christ...He lost himself in love.
Never put anyone out of your heart.
Love all men as God, even if they hurt you or shame you. Be like Gandhi and Christ.
Every line of the Hanuman Chalisa is a Mahamantra.
If you want to see God, kill desires. Desires are in the mind. When you have a desire for something, don't act on it and it will go away. If you desire to drink this cup of tea, don't, and the desire for it will go away.
The whole universe is our home and all residing in it belong to our family... instead of trying to see God in a particular appearance, it is better to see him in everything.
