One of my Favorites; Osiris was the Supreme Egyptian God of the Underworld, Brother and Husband to Isis, Father To Horus. He was worshiped as a Fertility, Resurrection, and vegetation God, I see where he comes in as a Fertility God because of how Isis conceived Horus after his brother Seth Killed him and chopped him up in bits and pieces, Isis and her sister Nephthys found all the pieces and put him back together again, cried out to Re to have pity on him, and then had Anubis and Thoth mummify him for awhile. Isis breathed life back into Osiris, and after that, Osiris impregnated her, and Horus was born. After Egyptians had died, they hoped to become one with Osiris, through him alone could immortality be achieved, in other words it was up to him if he thought they were worthy of being Reborn.
How you can bring him into your life; If you are looking to conceive or fertilize a garden or a plant, or if you are mourning a loved one, you can call upon Osiris for assistance
