The process of dealing therapeutically with planets is termed “Graha-Shanti” – which means “making peace with your planets.” We chant mantras, give charity, etc. as a means of dissolving tension between ourselves and a planetary karmic force. We can imagine that we are trying to change the planet’s attitude towards us, but it is more true to realize that we are trying to change our attitude towards the karma held for us by that planet. We are making peace with the planet, not cajoling the planet to make peace with us. Chanting a mantra for a specific planet, for example, will change our attitude towards that planet, and put us in a humble, receptive, devotional mood towards the destiny that planet holds for us. That change in attitude will change our subjective experience of our destiny – which is all important, for our lives are nothing but subjective experience.
