According to the Vajrayana teachings, there are ways to bring back the bardo being before rebirth takes place. Bardo being, the deceased who is in the intermediate state, is able to enjoy the offerings only through the blessing of samadhi, one-pointedness of mind or the sadhana of Vajaryana practice. The most important is to guide the deceased to Sukhāvatī by the power of meditative concentration.
The previously mentioned great terton used just this method to see his dead brother. His brother said to him, “I only had little more than thirty years to live, hardly long enough to enjoy the good times in life. I really don’t want to go to Sukhāvatī.” His brother also acknowledged this is karmic obstruction. It shows that when karmic obstructions are so great, even Amitabha’s pure land is made less enticing.
Therefore, it is important to train well while still alive as wrong thoughts may inadvertently turn up at the crucial moment otherwise. Only those who have been trained in these practices over a long period of time can maintain the right view at all times. After death, by praying to Amitabha, they can successfully take rebirth in Sukhāvatī.
