आण्डकोशो बहिरयं पञ्चाशत्कोटिविस्तृत: ॥ ४० ॥
āṇḍakośo bahir ayaṁ
This phenomenal material world is expanded to a diameter of four billion miles, as a combination of eight material elements transformed into sixteen further categories, within and without, as follows.
As explained before, the entire material world is a display of sixteen diversities and eight material elements. The analytical studies of the material world are the subject matter of Sāṅkhya philosophy. The first sixteen diversities are the eleven senses and five sense objects, and the eight elements are the gross and subtle matter, namely earth, water, fire, air, sky, mind, intelligence and ego. All these combined together are distributed throughout the entire universe, which extends diametrically to four billion miles. Besides this universe of our experience, there are innumerable other universes. Some of them are bigger than the present one, and all of them are clustered together under similar material elements as described below.
