Lord Brahma was created by Lord Visnu; then Lord Brahma created Lord Siva and other great sages, headed by Bhrgu Muni. These great sages included Bhrgu, Marici, Atreya, Vasistha and others. All these great sages were in charge of creating population. Since there were not very many living entities in the beginning, Visnu entrusted Brahma with the business of creation, and Brahma in his turn created many hundreds and thousands of demigods and great sages to continue with the creation. At the same time, Lord Brahma cautioned all his sons and disciples by reciting the prayers now recited by Lord Siva. The material creation means material engagement, but material engagements can be counteracted if we always remember our relationship with the Lord as that relationship is described in these prayers recited by Lord Siva. In this way we can remain constantly in touch with the Supreme Personality of Godhead. Thus despite our engagement in the creation, we cannot be deviated from the path of Krsna consciousness. The Krsna consciousness movement is especially meant for this purpose. In this material world everyone is engaged in some particular occupational duty which is prescribed in the varnasrama-dharma. Brahmanas, ksatriyas, vaisyas, sudras and everyone are engaged in their occupational duty, but if one remembers his first dutykeeping in constant contact with the Supreme Personality of Godheadeverything will be successful. If one simply executes the rules and regulations of the varnasrama-dharma in the role of a brahmana, ksatriya, vaisya or sudra and keeps busy and does not remember ones eternal relationship with the Lord, ones business and activities as well as occupational duties will simply be a waste of time. This is confirmed in the First Canto of Srimad-Bhagavatam (1.2.8):
