Dear @Dolly, we share your melancholy and grief but we all have to accept the destiny, as we are not left with any other way. Souls departed merge into greater energy. We earthlings, holding micros of the slightest part of it are no one to do something for them…..only our reverence and prayers are true homage to them.
Please do not worry for his well being. Disembarking the body, merged into the eternal, May the soul be in peace, should be our sincere prayer. Its my opinion that we should not try to mingle intensely and attract a departed soul. This gives them more pain.
Yes, we can support through VK, by passing our best prayers for its well being in its journey into the Divine. We may hold our VK between our palms and request VK for blessings of the Almighty for the departed Soul and give Peace and solace. You may offer Gangajal with Tulasi (Imagine it fill in your hands) to the departed soul, praying to rest in peace and may the Divine merge it eternally.
