one of my relative was with me recently. he met a sanyasi in the train who read the original manuscript of Nesfield(writer of grammer book). There Nesfield mentioned Past tense, present and future tense and said tense means tension. past and future gives tension.
The present was written without the word tense.I don't know whether the story is correct. But present is the god's present and
other two are tense(tension).
Sometimes when we empty ourselves of the past and the future we feel the emptiness of the present. In that emptiness can b deposited helpful console on present affairs that we often gather after r meditation session.
