Mantras for Graha Śānti according to Bṛhat Parāśara Horā Śāstra
These are the Vedic mantras as given by Parāśara in the Graha Śānti chapter. They were not put into the first volume of Science of Light as they are too complex for the average person.
In the translation below, I have tried to get the appropriate feeling of the verse- more than just a direct translation, yet trying not to stray from the direct translation, and yet still keep some poetic flow with a logical meaning. If any errors are noticed in the Sanskrit, please notify me. May the planets be pleased with you.
