The art of learning is that all good things do come to an end. But the testing part is trying to convince the ego that it’s ok to let that part of us go. The ego wants to attach itself to something that is no longer there.
As soon as you accept that this is all part of life the sooner you come to realise that hurtful emotions can no longer keep you anchored in the past anymore.
So raise your sails and let the winds carry you forth.
