Purport: 

Śrīla Prabhupāda comments: “In the rainy season, the clouds, tossed by the wind, deliver water, which is welcomed like nectar. When the Vedic followers, the brāhmaṇas, inspire rich men like kings and the wealthy mercantile community to give charity in the performance of great sacrifices, the distribution of such wealth is also nectarean. The four sections of human society, namely the brāhmaṇas, the kṣatriyas, the vaiśyas and the śūdras, are meant to live peacefully in a cooperative mood; this is possible when they are guided by expert Vedic brāhmaṇas who perform sacrifices and distribute wealth equally.”
