Aitreya Upanishad talks about a primitive life being formed at the time of origin of Universe. Maha Mrityunjaya Mantra talks about how this life spreads through Death.
Aitreya Upanishad talks about 3 forces that originated from Amba. They are Marichi(field of space that manifests itself as a quanta on matter), Maram (particles of matter that are of mortal form) and Apa (Primitive Life being).
