The Noble Mahayana Sutra The Wisdom of the Hour of Death

In response to a question from the bodhisattva Akashagarbha, the Buddha explains how a bodhisattva should view the mind at the moment of death. It is important, the Buddha says, to cultivate the perception of insubstantiality, great compassion, referencelessness and non-attachment, and not to seek buddhahood anywhere other than in the mind’s own wisdom.
