Expansion (projection) of soul-units (outside the body) related with Āhāraka Śarīra (conveyance body)- A type of Samudghāta (expansion of the soul-units beyond the body);
when an ascetic, endowed with the power potential of conveyance body, creates the conveyance body to send it outside, he expands his soul-units outside his Audārika Śarīra (gross body). Such projection, in diverse directions, of the soul-units is Āhāraka Samudghāta. It depends upon the Nāma (body-making) Karma qua Āhārakaśarīra.
