1) Chi lu puja (betraying the death).You can ask Geshe Ngawang Drakpa to do this.
2) Paint the Boudha and Swayambhunath stupa. This also entails offering umbrellas and banners to the stupas. [Note: This is something that Rinpoche does every month ; it costs about $350 to do this offering. Kopan Monastery takes care of this, but it can be arranged for you, or you are welcome to do it.]
3) The whole Prajnaparamita needs to be read. This takes about seven days. The Gyume monks in Dharamsala come out best to do this for you, so for this you can email the director of Tushita Centre and ask her to arrange it. Ask for the cost first and also work out the food offering and the offering to each monk. The director of Tushita can give you some guidance about this; she may know what is normal.
4) It is most important for you to do White Heruka practice every day in the early morning, for the next four months.
You need to do more purification practice and collect merit; it seems there is something heavy. Also do tonglen more, as well as practicing the five powers in your life as well as at death time. [Find links to the booklet Practicing the Five Powers Near the Time of Death in the FPMT Catalogue.] Pay attention to this practice and study it more. It is good to make preparation, anyway. With the world situation now and all the disasters, it is more possible to die than to live, so it is wise to think like this, to prepare for death now and not to think that you will live forever.
