Vamana Avatara is the fifth incarnation of Vishnu. This is the first Avatara where Lord Vishnu took complete human form as a dwarf at the beginning. The uniqueness of this Avatara is that Vishnu did neither use any weapon nor kill any asura. The only weapon he used was that of begging in front of King Bali as a Brahmachari. And then, he tricked and conquered him in a soft way. It may be said that unlike other Avataras, Vamana Avatara was a Sattvik Avatara.
