Tantra Master

Here is the website by ma krishna Radha : http://www.tantralife.com/english/default.htm , a long time osho sannyasin.
I read her book on tantra and i can say that the essence of her book is described in the following quote on the front page of her website:

"Generally what we call love,
it's not true love.
We ask, we demand.
Ordinary love is a kind of begging:
"Give me more, give me more!".
True love says: " ask me more, take more".
When love is giving, it is true.
When it longs to have, it is false.
And when love is giving,
it spreads, it pulsate."
