We should never lose sight of the importance of having an insight into the pure nature of Mind (citta) which is distinct from the maculate or defiled mind. Nor should we forget that while mind is tethered to the temporal body, it is potentially free of the body which, when properly trained, after the dissolution of the body, will go to a higher plane.
In the Mahanama Sutta (S. v. 370) of the Pali Canon we learn that Mahanama who is visiting the Buddha was distressed. He confesses to the Buddha of his fear that when passing through the crowded streets of Kapilavatthu he might come to an untimely death.
The Buddha, of course, assures Mahanama that he need not worry about the afterlife if he should happen to die. The Buddha uses the following illustration.
“Suppose, Mahanama, a man submerges a pot of ghee [clarified butter] or a pot of oil in a deep pool of water and breaks it. All of its shards and fragment would sink downwards, but the ghee or oil there would rise upwards. So too, mahanama, when a person’s mind has been fortified over a long time by faith, virtue, learning, generosity, and wisdom, right there crows...or various creatures eat his body... But his mind, which has been fortified over a long time by faith, virtue, learning, generosity, and wisdom—that goes upwards, goes to distinction” (trans., Bhikkhu Bodhi).
An important element in the above is that our mind is potentially liberated and can become fully liberated, in time, with thorough development (paribhrita) once a glimpse into Mind’s immaculate nature is gained. Another important element is that when the body meets its death, Mind does not. In virtue of one’s spiritual efforts, Mind separates from its former ties with the phenomenal body, going to distinction (vishesha) very much like oil which, being lighter than water, rises upwards away from the shards and fragments of the broken pot.
