If we want to recite the Gayatri Mantra, we shall have to dispossess our mind of hatred, and throw out all feelings of jealousy and enmity; only then we can achieve the state of being happy. Miseries do come in life and if we lose our patience and our mental balance, we shall retain base thoughts. It is thoughts which disturb us. It is the heart that brings us sorrow and it is the same heart that brings gladness. So life can be hell or heaven, the result of thoughts. This world is what we think it to be.
