This is the nineteenth entry from my fieldwork diary. The original date is 22.09.2010.
*I was unable to go so my mother wrote instead of me this time.
"Vajrasattva is a very powerful mantra. It purifies our past life karma.
If all we know are the teachings of the dharma and we do not practice then there is no benefit. So we must practice every day. Visualize the root lamas - they gives us their blessings.
We accumulate good merit when we meditate on loving kindness and compassion. Gewa - sharing the joy with other people.
In this life we have difficulties in our daily lives so reciting a mantra will purify all negative emotions and thoughts. A person with a strong ego destroys their Buddha-nature by letting the ego rule them. Through three "doors" - body, mind and speech - we can purify ourselves. Even just chanting one mantra can destroy all the negative karma from past lives.
You must wish for it and have motivation to become pure through meditation. Milarepa also did this. Vajrasattva is a high and secret tantra practice. The mantra is very long but the short version is simply OM VAJRASATTVA HUM. Chant this, confess and visualize the Vajrasattva to purify yourself if you've made a mistake."
