Death is not Protestant, Catholic, Islamic, Judaic, Hindu or Buddhist, although often hijacked by these. Neither can it be explained by theories or philosophies. It belongs to none of these. If anything Death belongs to life. It cannot be solved by the mind. This is its beauty and its enigma. Only silence can express the 'Power That Knows the Way' and this statement is of course a concept too.
The fake self that wants to stake a claim for itself in ever more subtle ways would love the consolation and boost of a solution. Of course the real relief comes when the person is found out to be a fabrication and the river flows unimpeded.
