Think of death – think of it often – think of it each and every day. Socrates said, “Death may be the greatest of all human blessings.”
Imagine how intense and alive you would be if you live your life taking each day as if that it is the only day you have! There would be no time for past regrets or future worries.
The Sufi poet Rumi says “die before you die” embodying the wisdom that lives each moment in totality, in its full measure. Then, when the moment ends, there is no pain.
When living in the moment has been complete and absolute, you experience nirvana!
