The meaning of the word “Yoga” is “union”. It is derived from the Sanskrit root “yuj,” (pron. “yug”) meaning “to join”, “to unite” but also “to subjugate”, with the meaning also “to control” and “to disciplinate”. The English word “yoke” is also derived from the same Sanskrit (Indo-European) root. Yoga means union of the individual consciousness or soul with the Universal Consciousness or Spirit. Some call yoga a moving meditation. This article from headspace talks about the benefits of Shavasana, savasana, or corpse pose, the yoga meditation for relaxation. If you’ve floated before, you can probably see where this is going. You can think of your float session as an extended Shavasana, really helping you get connected and in tune with the universal consciousness.
