This moment, this now is extremely important. It is all we humans know. Thoughts created instantaneously become the past. They are behind us. Take the first lines of this post ... Moments later now from when they were written, are now in the past.
To manifest our future we have to be fully incorporated in the moment. Sadly for many of us, the now moment is filled with worries and woes from the past. That is the characteristics of being in a material world.
To be in the moments is to merely observe your thoughts.
