Stainless Pinnacle Mantra Required for Stupas
Rinpoche checked and found some of the mantras that must be placed inside stupas were missing. One of these is the Stainless Pinnacle mantra, which consists of both a root mantra and a heart mantra. Rinpoche also advised researching the longevity of microfilm.
Whoever builds stupas, especially bigger ones, you must put the Stainless Pinnacle mantras inside. 100,000 copies of this mantra should be put into stupas. Some of the 100,000 should be the root mantra, however, most can be the heart mantra. Then, from that, it becomes so easy to develop everything—internally as well as externally.
Also, the more people who are involved in building holy objects the better. Involvement can be as a donor offering money or offering work by actually doing the physical labor of building the stupa. When more people are involved that increases the merit so much and makes it one hundred times more powerful, just like doing prayers together.
Someone should do research on how long microfilm lasts and how it is affected by heat and cold and moisture. Maybe check how the microfilm looks inside prayer wheels that were filled long ago.
