Srimad Bhagavatam Canto 08, Chapter 14, Text 05

SB 8.14.5

tato dharmam catuspadam
 manavo harinoditah
yuktah sañcarayanty addha
 sve sve kale mahim nrpa
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Thereafter, O King, the Manus, being fully engaged according to the instructions of the Supreme Personality of Godhead, directly reestablish the principles of occupational duty in its full four parts.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Dharma, or occupational duty, can be established in its full four parts as explained in Bhagavad-gita. In Bhagavad-gita (4.1) the Lord says:
 
imam vivasvate yogam
 proktavan aham avyayam
vivasvan manave praha
 manur iksvakave ’bravit
 
“I instructed this imperishable science of yoga to the sun-god, Vivasvan, and Vivasvan instructed it to Manu, the father of mankind, and Manu in turn instructed it to Iksvaku.” This is the process of disciplic succession. Following the same process, the Krsna consciousness movement is teaching the principles of Bhagavad-gita as it is, without deviation, all over the world. If the fortunate people of this time accept the instructions of Lord Krsna, they will certainly be happy in Sri Caitanya Mahaprabhu’s mission. Caitanya Mahaprabhu wanted everyone, at least in India, to become a preacher of this mission. In other words, one should become a guru and preach the Lord’s instructions all over the world for the peace and prosperity of humanity.
