A Tsunami has a Talispin, and Difficulties will Disapear

My grandson is now in high school, and I have a grand-daughter, soon to follow. Some day I will be a Great grand-father, and I, not seeking vain desires, will pass away as any other.
But I will leave behind me, and even after my death, a Great Tsunami.
For you young people here, I remind you.

An edified tsunami has a talispin, and difficulties disappear and obstacles vanish.
