But if i may ask, is there a level higher then this?
How does one know which direction is one going in if the path we are travelling on is our own and its not a blazed trail?
One does not know when or how it will come back. So why even worry??
Why just not follow one's own heart and always strive to do the right thing and be thankful for the courage given to you to be able to do that?
Once "you" have emptied "you cup", drop the "you"
If we plot the past through the present, we can see the direction we are heading. Very few of us (and certainly not me) are off a well worn path.
We don't need to know when and where, only that it does.
The heart is just too often associated with the feelings and not with wisdom or ethics.
Only my simple thoughts on your deep questions.
