Tantra: The Supreme Understanding is the first book on Tantra that I have read. And I am not sure if I could have had a better author to read than Osho. In his ever simple way, he explains the path of Tantra. Tantra like all other ways that seekers adopt is a path of knowing oneself. He explains that yoga is a way of warriors and tantra is the path of royal. This is the reason you have to fight all the time on the path of yoga. The yogic path divides everything into two: good and bad, heaven and hell. And you are always fighting one to achieve the other. On the other hand path of Tantra does not require you to do anything.
It just requires you not to see duality, and accept everything equally. As it knows that both divisions are a part of one whole, and the existence of one means the existence of the other. It says to focus on nothing and you have everything.
He so simply tells you to just live, live in the moment. Be at peace with yourself, and everything else will follow. He talks about Tilopa and his disciple Naropa, who are not known to many people. But according to Osho that is because there was no need for them to tell people what they have experienced. And a teacher like Tilopa will not give knowledge to anyone till he is very sure that the student is ready. In all his life he could find only one student Naropa, and he was happy with one student. There was no need to enlighten everyone on the face of the earth.
He talks about Mahamudra and the two stages that happen before that. All this must be not so easy to achieve as there are not many people have been able to. But Osho makes it sound so simple that you feel that you are almost there and about to achieve it, it is within your arms reach.
Read Tantra: The Supreme Understanding if you are curious about Tantra and of course if you enjoy reading Osho.
