Tantra means to “stretching beyond limitation” or “to weave.”
In many styles of yoga, there is an emphasis on one or two areas of practice, like asana and pranayama.
In tantric hatha practices, we often weave together many different techniques like asana, bandhas, chanting, pranayama and meditation. Our aim is to carefully bring together these elements and utilize the practices so that our energy feels more concentrated and more contained, so we may feel less reactive, more free, more balanced, centered, and connected to our own power.
In tantra, we are looking for freedom in this world, not from this world.
Classical yoga points to managing our mind in order to manage our energy. Tantra ask us to manage our energy in order to consciously direct our mind. This is a different approach for the same outcome; achieving the state of yoga, or union.
