What has not come yet has not come yet. Don't unnecessarily waste your time and energy in imagination, because no imagination is ever fulfilled. It is because of this that the proverb exists in every language: "Man proposes, and God disposes" because you imagine a certain thing in the future, and it is never so.
Withdrawing yourself from past and future, you will become a tremendously intense energy, focused in the present, concentrated in the present like an arrow.
Each moment being aware, alert, watchful, in the herenow, is the way not to miss the train. Every experience needs your presence here, this moment.
And this is a simple secret, but it opens the doors of existence, of all the mysteries, of all that is worth knowing, worth tasting, worth feeling, worth being.
