अव्यक्ताद्व्यक्तयः सर्वाः प्रभवन्त्यहरागमे।
रात्र्यागमे प्रलीयन्ते तत्रैवाव्यक्तसंज्ञके।।8.18।।
।।8.18।।ब्रह्माजीके दिनके आरम्भकालमें अव्यक्त(ब्रह्माजीके सूक्ष्मशरीर) से सम्पूर्ण प्राणी पैदा होते हैं और ब्रह्माजीकी रातके आरम्भकालमें उसी अव्यक्तमें सम्पूर्ण प्राणी लीन हो जाते हैं।
8.18 Ahar-agame, with the coming of day, at the time when Brahma wakes; sarvah vyaktayah, all manifested things, all things that get manifested, all creatures characterized as moving and non-moving; prabhavanti, emerge, become manifested; avyaktat, from the Unmanifested-avyakta (Unmanifested) is the state of sleep of Prajapati; from that avyakta. Similarly, ratri-agame, when night comes, at the time when Brahma sleeps; praliyante, they, all the manifested things, merge; tatra eva, in that itself; avyakta-sanjnake, which is called the Unmanifested referred to above. In order to obviate the defect of the emergence of some unmerited result and the destruction of merited results; [The following verse says that the very same multitude of beings continues in the different cycles of creation, and there-fore these two defects do not arise.] for pointing out the meaningfulness of the scriptures [For the earlier reason the scriptures do not lose their validity.] dealing with bondage and Liberation; and with a view to propounding detachment from the world on the ground that the helpless multitude of beings perishes after being born again and again under the influence of accumulated results of actions that have for their origin such evils as ignorance etc. [The five evils are: ignorance, egoism, attachment, aversion and clinging to life. (See P. Y. Su. 2.3)], the Lord says this:
8.18 See Comment under 8.19
8.18 Thus, at the dawn of a day of Brahma, the manifest entities existing in the three worlds, possessing body, senses, objects, and places of enjoyment appear from the non-manifest (Avyakta), which is the condition of Brahmas body in that state, and at the beginning of the night they are dissolved into the condition of the unevolved (Avyakta) which forms the body of Brahma then.
