The Buddha recited the poem:
‘Let not a person revive the past
Or on the future build his hopes,

For the past has been left behind
And the future has not been reached.

Instead, with insight, let him see
Each presently arisen state;
Let him know that and be sure of it,
Invincibly, unshakeably.

Today, the effort must be made;
Tomorrow, Death may come, who knows?
No bargain with Mortality
Can keep him and his hoards away.

But one who dwells thus ardently,
Relentlessly, by day, by night –
It is he, the Peaceful Sage has said,
Who has one fortunate attachment.’

Then the Blessed One rose from his seat and entered his dwelling.

Quotes

on asteya (one of the five yamas)…
‘Any selfish act is acting without asteya, it is taking somehow, maybe taking someone else’s choice or freedom or opinion. It is about being aware not just of myself but of others, how do I interact with others (for instance not jumping in during a conversation, which I do too often).
There is an enormous aspect of letting go, especially for me, letting go of a need to control. It is basically trust.’
