Every line of the Hanuman Chalisa is a Mahamantra.

Everything is impermanent, except the love of God.

Often one goes for one thing and finds another

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.

Whatever may be guru - he may be a lunatic or a common person. Once you have accepted him, he is the lord of lords.

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.

Love everyone, serve everyone, remember God, and tell the truth.
