As stated in Bhagavad-gÄ«tÄ (8.17):
sahasra-yuga-paryantam
ahar yad brahmaṇo viduḥ
rÄtriá¹ yuga-sahasrÄntÄá¹
te ’ho-rÄtra-vido janÄḥ
“By human calculation, a thousand ages taken together is the duration of BrahmÄ’s one day. And such also is the duration of his night.†BrahmÄ’s one day consists of one thousand cycles of the four yugas — Satya, TretÄ, DvÄpara and Kali. In that one day there are fourteen manvantaras, and out of these manvantaras this CÄká¹£uá¹£a manvantara is the sixth. The various Manus existing in one day of Lord BrahmÄ are as follows: (1) SvÄyambhuva, (2) SvÄrociá¹£a, (3) Uttama, (4) TÄmasa, (5) Raivata, (6) CÄká¹£uá¹£a, (7) Vaivasvata, (8) SÄvarṇi, (9) Daká¹£asÄvarṇi, (10) Brahma-sÄvarṇi, (11) Dharma-sÄvarṇi, (12) Rudra-sÄvarṇi, (13) Deva-sÄvarṇi and (14) Indra-sÄvarṇi.
Thus there are fourteen Manus in one day of BrahmÄ. In a year there are 5,040 Manus. BrahmÄ has to live for one hundred years; consequently, the total of Manus appearing and disappearing during the life of one BrahmÄ is 504,000. This is the calculation for one universe, and there are innumerable universes. All these Manus come and go simply by the breathing process of MahÄ-Viṣṇu. As stated in the Brahma-saá¹hitÄ:
yasyaika-niÅ›vasita-kÄlam athÄvalambya
jÄ«vanti loma-vilajÄ jagad-aṇá¸a-nÄthÄḥ
viṣṇur mahÄn sa iha yasya kalÄ-viÅ›eá¹£o
govindam Ädi-puruá¹£aá¹ tam ahaá¹ bhajÄmi
The word jagad-aṇá¸a-nÄtha means Lord BrahmÄ. There are innumerable jagad-aṇá¸a-nÄtha BrahmÄs, and thus we can calculate the many Manus. The present age is under the control of Vaivasvata Manu. Each Manu lives 4,320,000 years multiplied by 71. The present Manu has already lived for 4,320,000 years multiplied by 28. All these long life spans are ultimately ended by the laws of material nature. The controversy of the Daká¹£a-yajña took place in the SvÄyambhuva manvantara period. As a result, Daká¹£a was punished by Lord Åšiva, but by virtue of his prayers to Lord Åšiva he became eligible to regain his former opulence. According to ViÅ›vanÄtha CakravartÄ« ṬhÄkura, Daká¹£a underwent severe penances up to the fifth manvantara. Thus at the beginning of the sixth manvantara, known as the CÄká¹£uá¹£a manvantara, Daká¹£a regained his former opulence by the blessings of Lord Åšiva.
