The “Age of Quarrel and Hypocrisy” The fourth and last age in the cycle of a mahā-yuga. This is the present age in which we are now living. It began 5,000 years ago and lasts for a total of 432,000 years. It is characterized by irreligious practice and stringent material miseries. In the Śrīmad-Bhāgavatam the age is personified as an evil black man who tries to kill a helpless cow and bull. The four legs of the cow represent the four principles of religiosity-namely, truth, cleanliness, mercy and austerity. The bull represents religion itself; The most recommended process of spiritual upliftment in this age is saṅkīrtana, the congregational glorification of the Lord through chanting His holy name.
