Hanuman, the devotee of Rama, said: When I identify myself with the body, O Lord, I am Thy creature, eternally separate from Thee. When I identify myself with the soul, I am a spark of that Divine Fire which Thou art. But when I identify myself with the Atman, I and Thou art one.
Darkness cannot drive out darkness; only light can do that. Hate cannot drive out hate; only love can do that.
We all have the power of thought – so what are you lacking? If you have willpower, then you can change anything. It is usually said that you are your own master.
A yogi who perceives his real Self as separate from his active senses and their objects never becomes attached to anything. He is aware of the dream nature of the universe and watches it without being entangled in its complex but ephemeral nature.
