By human calculation, a thousand ages taken together is the duration of Brahmas one day. And such also is the duration of his night. Brahmas one day consists of one thousand cycles of the four yugasSatya, Treta, Dvapara and Kali. In that one day there are fourteen manvantaras, and out of these manvantaras this Caksusa manvantara is the sixth. The various Manus existing in one day of Lord Brahma are as follows: (1) Svayambhuva, (2) Svarocisa, (3) Uttama, (4) Tamasa, (5) Raivata, (6) Caksusa, (7) Vaivasvata, (8) Savarni, (9) Daksasavarni, (10) Brahma-savarni, ( 11) Dharma-savarni, (12) Rudra-savarni, (13) Deva-savarni and (14) Indra-savarni.

The word jagad-anda-natha means Lord Brahma. There are innumerable jagad-anda-natha Brahmas, 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 Daksa-yajna took place in the Svayambhuva manvantara period. As a result, Daksa was punished by Lord Siva, but by virtue of his prayers to Lord Siva he became eligible to regain his former opulence. According to Visvanatha Cakravarti Thakura, Daksa underwent severe penances up to the fifth manvantara. Thus at the beginning of the sixth manvantara, known as the Caksusa manvantara, Daksa regained his former opulence by the blessings of Lord Siva.
