The mind has a hard time with Trust.
The mind wants to know, "Why should I trust? How do I know that what I'm trusting in is 'right' or 'true'? How do I know I'm not trusting in vain?"
I was doing this whirlwind within myself a while ago and came to this conclusion: It doesn't actually matter.
I don't trust because I claim to know what will happen.
I trust because it feels good to trust.
I can't be out in the future knowing what will happen. I can't be back in the past changing what already happened.
All I can do is be here, in this present moment. And in this present moment, the thing that feels best, is Trust. <3
