The residents of the earth in Satya-yuga are described as having all good qualities. In Tretā-yuga human society is described as dharmiṣṭhāḥ, or thoroughly religious, and brahma-vādinaḥ, or faithfully seeking the Absolute Truth through the Vedic injunctions. However, it should be noted that all of the exalted qualities of the people of Satya-yuga are not mentioned in this verse. In other words, in Satya-yuga people are automatically perfect, whereas in Tretā-yuga people are inclined to become perfect through performing Vedic sacrifice. In Tretā-yuga human society is not automatically Kṛṣṇa conscious, as it was in Satya-yuga, but people are still highly inclined to become Kṛṣṇa conscious, and thus they strictly follow the Vedic injunctions.
