There is the same akasa both in the microcosm and in the Macrocosm.

(6-8) Correspondences as to the Sun, the Moon and the Soul.

19. The Sun and the Moon, the regulators of time, are the prana and the apana of the embodied beings (i.e., in the microcosm). The witness (within) is the Purusha (without).

That is to say, the personal soul in the microcosm corresponds to the cosmic soul, the Hiranyagarbha in the macrocosm.
