Basic requirement of spirit is peace whichever body it bears on the cord of life but every one needs peace at its best.
What one needs hereafter at is foremost that is peace and peace alone is prayed for departed soul.
Peace of mind is prime subject for human too, though it is tough but attainable through adoration of Vedic prescription on the subject.
Eternal peace is foremost subject for spirit because without which it is really tough to reach at the true conscious state that makes one to experience bliss.
Let there be peace among all beings, let there be peace through existence of celestial bodies, let there be peace permeates, space, earth, herbs and foliage, let peace be the personality of human on the planet.
May lord bless all.
Thanks please
