Many of you might have seen this quote and image in some way or combination like this or the one below:

My definition of the present moment to make actually sense of it:
- It’s the pre-sent moment, the moment that was sent to you by your higher self.
- It’s the moment that was “pre”, so before the thought.
- It’s the “present”, the moment as a present, a gift to you.
So, that’s the image I show to myself every day to remind my self of what the “present moment” means:
The moment before the thought, the moment that’s a present/gift for you, and the pre-sent moment from your higher self to your self.
Why? Because once you understand it, you can always go “back” to that “pre”-sent moment, that moment before something happened or before you thought something.

Let’s say you got into overthinking – and you can’t make your mind about something, then you go into the pre-sent moment, the moment before that thought. You just stay in the now, in the present – because there everything is fine, there is no thought, and just peace.
And if you are again in your thoughts, then you know: You are not in the pre-sent-moment-before-the-thought. You are lost in the thought, in your mind, in your future, in your past, you might be anywhere, but not in the present moment.
And while speaking of that, how could I not recommend the “Power of Now”:

One way to understand it:
The present moment is a gift from your true self, a peaceful place before any thoughts, where everything is just okay.
