Do you mean like gathering Manna from heaven? My understanding (hope I am not confusing myself with two different stories) is the Jews were going through the dessert back a long time ago, it was rough going with little food, when white colored food came down out of the sky.
This food came like a magical answer to prayers. Have you seen spider webs (with eggs) of some spiders that fly like pancake size white clusters in the sky carried by the wind? This happens only with certain spiders under certain natural weather conditions certain times of the year but not every year (where the baby spiders are birthed on the thick leaved branches of the bay tree and other similar trees that are actually not friendly to ants but heaven to these spiders). in right circumstance of weather and condition of these trees and breezes, nature or the will of God decides these babies should not be hatched on the tree, rather these web clusters take off high into the sky and fly even hunderds of miles to distrubute the spider elsewhere.
They can become quite pancake or bun like, and are edidable. Quite tasty, I have heard, though their whiteness gathers some dust sometimes and get sort of dusty colored.
I suspect this was the Manna - not that it would not be a magical moment and answer to prayers. Nature feeds many in cycles and for reasons. But the webs are best grabbed at low altitude or when landed in the grass of other but will start to decay so you have to gather fast. But more may be coming.
Now I could be wrong, the Manna might have been something else, but it was about this "nick of time" food and arriving almost like magic. When it arrives, don't be lazy but gather at that time during the bleak situation and enjoy.
The Manna though rare, also has curative powers, rejuvenational in nature.
In Hinduism, at a bleak moment when hope is lost almost, we find examples of Manna from nature as a sacred thing from God with curative powers. For example, in the Hindu Ramayana, When Lakshmana is severely wounded during the battle against Ravana, Hanuman is sent to fetch the Sanjeevani herb/plant/bark (with sap, sometimes described as glowing and resin like) a powerful life-restoring "herb" from Dronagiri mountain, in the Himalayas, to revive the fallen Lakshman after a battle. Hanuman flys to go get it.
Some consider this cure a magic herb and rare.
So there are examples of manna from heaven in Hinduism IMHO. I know you might be speaking metaphorically, which is fine, too. Yes there are some Hindus who also believe in gathering both physical concoctions with powers and spiritual ones with powers and even metaphorical symbols called yantras or mystical diagrams-plates with triangles on them and such which do possess "magical" transformational powers.
