The physical activity of the combined function of the gross body with other type of bodies, viz., Karmaṇa/Vaikriya/Āhāraka, which is of four kinds-
1.When a Jīva (soul), on taking birth in the human or sub-human Gati (realm of mundane existence), appropriates the aliment in the first Samaya (smallest time-unit), but at that time building of the Śariraparyāpti (bio-potential qua body) is not yet completed, there is combination of the activity of Audārikaśarīra (gross body) with the Kārmaṇaśarīra (subtle most body formed by Karma-pudgalas (material clusters qua Karma)).
2.When a human or a sub-human being equipped with the Vaikriya Labdhi (supernatural power of creation of protean body), creates a protean form, but till the formation of protean body is not completed, there is combination of the activity of Audārikaśarīra (gross body) with that of the Vaikriya (protean) body.
3.When a yogi (an ascetic), equipped with the Āhāraka Labdhi (supernatural power of creation of conveyance body) creates an Āhārakaśarīra (conveyance body), but till the formation of such body is not completed, there is combination of the activity of Audārikaśarīra (gross body) with that of the Āhārakaśarīra.
4.When a Kevalī (the omniscient soul) undertakes Samudghāta (expansion of soul-units outside the body), in the second, sixth and seventh Samayas (smallest time-unit) of the operation, there is combination of the activity of Audārikaśarīra (gross body) with that of the Kārmaṇaśarīra.
