I keep on getting fascinated by Harivansh Rai Bachchan. His poems and sheer richness of the words are overwhelming. There is less known poem of his (Madhushala is so famous, sometimes I feel it's a little overshadowing) and it's called Nagin. It's my all time favorite because of it's expression, flow, and the hidden symbolism. For those who know hindi:
Tu Preeti, Bheeti, Aasakti, Gruna ki ek visham sangya bankar,
Parivatit hone ko aai mere aage kshan pratikshan mein,
Nartan kar nartan kar nagin mere jeevan ke aangan mein.
