My very dear Marion,
Thank you very much for your kind letter. It is amazing what you want to offer back to those ants. It is incredible! The thought to take precepts for each ant would not have come into my head. I am sure all the ants will jump up and down and clap their hands and have a party for you when you finish, wishing for you to receive all happiness…ha ha ha. I put my hands together at my heart thanking you very, very much on behalf of all the ants.
In addition, read the Diamond Cutter Sutra four times, and then recite the long Namgyalma mantra 21 times, if possible, or else seven times, and dedicate the merit to the ants’ quick enlightenment. They might become your disciples and do everything you say.
Big love and prayers...
