Any material form, or thought, or feeling, past or present, should be regarded as, 'This is not mine, this is not what I am, this is not my self.'
Just as a snake sheds its skin, we must shed our past over and over again.
Within this moment, the only moment that exists, the past, present and future are contained.
Let go the past, let go the future, and let go the present (front, back, middle). Crossing to the farther shore of existence, with mind released everywhere, do not further undergo birth and decay.
