In the last few years I have taken some interest in Akshobhya and we have offered the fire puja of Akshobhya at the Kagyu Monlams. I have also created some Akshobhya retreats here with Lamas from different countries and tried to explain what I knew about this practice. One reason I did this is because technical and material progress in the 21stcentury means that the activity of human beings is very powerful and has a great effect, unlike in ancient times. We harm other beings and the environment very much. Thus it is an age when we are creating very strong negative karma. Therefore if we practice Akshobhya, I think it will help a lot because Akshobhya is a Buddha especially meant to purify negative karma.
