A single cell becomes the whole body. Somewhere it is nails, somewhere it is nose and tongue but all is a manifestation of a single cell. In the same way, the entire universe is made up of a single substance.

Remembering and FEELING that everything is made up of one thing heals the body and mind and balances the doshas in the body (vata, pitta and kapha). This is savitarka samadhi. Savitarka samadhi means equanimity with logical awareness.

Deep sleep can be jada samadhi (equanimity with inertia). And hence, sleep is the main factor in healing. Even medicines will not help without sleep and rest.

Samadhi with ecstasy has no logic. This is nirvitarka samadhi, awareness with bliss.

Nirvitarka samadhi is even beyond the experience of bliss, undefinable beyond words.
