He has portrayed galaxy of characters such as thieves, drunkards, rascals, mentally-retarded, morally-lost, and spiritually deprived men as well as men of high intellectual abilities, philosophic insights, deep-rooted moral visions and great spiritual capabilities. He has projected all walks of life in his fiction such as romantic dreamers and down to earth realists, innocent and corrupt, satanic tempters to the redeemers of mankind- all types of men and women appear in his works.
