The word Tantra is derived from the Sanskrit roots Tan and Tra. The root Tan means extension, expansion, a stretching and pulling, as you pull the rubber. Tra means to liberate, to release, to emancipate, to make free.

And what does Yoga mean?  Yoga means a process of fission of matter and energy and ultimately a process of fusion. The meaning of Tantra and the meaning of Yoga is the same but somehow today in this part of the world, and in other parts also, the Yoga teachers would prefer to call themselves Yoga teachers but they are afraid to say that they teach Tantra.  I teach Tantra.  Why not, if it is something very nice, if it is going to clear up your personality, your deep rooted complexes, going to correct your behavior, is going to rehabilitate you psychologically, and physically? Why should you not take it up?

Yoga and Tantra are 2 different words belonging to the same way of life.  Yoga is an offshoot of Tantra. 

Yoga is not only Yoga but it is Tantra. But there is a difference, though only a little. Whereas in Yoga there are a lot of restrictions, in Tantra there are no restrictions. 

Tantra does not accept any kind of religious, cultural or tribal or national inhibitions. 

A teacher in Tantra or the philosophy of Tantra is aware of the variations in human behavior. Tantra accepts that three billion people cannot belong to only one range of life. We are evolving, mentally, physically, intellectually, emotionally, morally and ethically also and this evolution is constant and this evolution is sure and certain. This evolution is controlled by the collective nature Prakriti, and this evolution the Tantra respects.
