In former ages such as Satya-yuga human beings were perfectly qualified and easily performed even the most difficult spiritual processes, meditating for many thousands of years practically without eating or sleeping. Thus, although in any age one who completely takes shelter of the Lord’s holy name gets all perfection, the highly qualified inhabitants of Satya-yuga do not consider that merely moving the tongue and lips, chanting the Lord’s holy name, is a complete process and that the Lord’s holy name is the only shelter within the universe. They are more attracted to the difficult and elaborate yoga system of meditation, complete with sophisticated sitting postures, painstaking control of the breath and deep, extended meditations in trance on the Personality of Godhead within the heart. In Satya-yuga sinful life is practically unheard of, and therefore people are not afflicted with the terrible reactions seen in Kali-yuga, such as world war, famine, plague, drought, insanity, etc. Although in Satya-yuga people always worship the Personality of Godhead as the ultimate goal of life and meticulously follow His laws, called dharma, they do not feel themselves to be in a helpless condition, and thus they do not always experience intense love for the Lord.
