Trust is simple. It is just like a child trusts in his mother.
It is not that he believes — belief has not yet entered.
You were a small child once.
Did you believe in your mother or did you trust her?
The doubt has not arisen so what is the question of belief?
Belief comes only when the doubt has entered; doubt comes first.
Later on, to suppress the doubt, you catch hold of a belief.
Trust is when doubt disappears; trust is when doubt is not there.
For instance, you breathe. You take a breath in; then you exhale, you breathe out.
Are you afraid of breathing out, because who knows, it may not come back? You trust.
You trust it will come.
Of course there is no reason to trust, what is the reason?
Why should it come back?
You can at the most say that in the past it has been happening so — but that is not a guarantee.
It may not happen in the future.
If you become afraid of breathing out because it may not come back, then you will hold your breath in.
That's what belief is — clinging, holding. But if you hold your breath in, your face will go purple and you will feel suffocated. And if you go on doing that, you will die.
All beliefs suffocate and all beliefs help you not to be really alive. They deaden your being.
