Ardhanarishwar

Now modern psychology,
Depth psychology particularly,
Says that man is both man and woman.
No man is just male
And no one is just female;
Everyone is bi-sexual.
Both sexes are there.
This is a very recent research in the West,
But for Tantra
this has been one of the most basic
concepts for thousands of years.
You must have seen some pictures of Shiva
as ardhanarishwar: half man, half woman.
There is no other concept like it
in the whole history of man.
Shiva is depicted as
half man, half woman.
