“So we have the Madan, a generic name indicating wicked elemental spirits, half brutes, half monsters, for Madan signifies one that looks like a cow. He is the friend of the malicious sorcerers and helps them to effect their evil purposes of revenge by striking men and cattle with sudden illness and death.
The Shudala-Madan, or graveyard fiend, answers to our ghouls. He delights where crime and murder were committed, near burial spots and places of execution. He helps the juggler in all the fire-phenomena as well as Kutti Shattan, the little juggling imps. Shudala, they say, is half-fire, half-water demon, for he received from Siva permission to assume any shape he chose, transform one thing into another; and when he is not in fire, he is in water. It is he who blinds people “to see that which they do not see.”
Shula Madan, is another mischievous spook. He is the furnace-demon, skilled in pottery and baking. If you keep friends with him, he will not injure you; but woe to him who incurs his wrath. Shula likes compliments and flattery, and as he generally keeps underground it is to him that a juggler must look to help him raise a tree from a seed in a quarter of an hour and ripens its fruit.
Kumil-Madan, is the undine proper. He is an elemental spirit of the water, and his name means blowing like a bubble. He is a very merry imp; and will help a friend in anything relative to his department; he will shower rain and show the future and the present to those who will resort to hydromancy or divination by water.
Poruthu Madan, is the “wrestling” demon; he is the strongest of all; and whenever there are feats shown in which physical force is required, such as levitations, or taming of wild animals, he will help the performer by keeping him above the soil, or will overpower a wild beast before the tamer has time to utter his incantation. So, every “physical manifestation” has its own class of elemental spirits to superintend them.”
