Highest perfection (SB cantos 4 - 12)
Srimad-Bhagavatam
SB Canto 4
Bhṛgu Muni, in cursing Nandīśvara, said that not only would they be degraded as atheists because of this curse, but they had already fallen to the standard of atheism because they had blasphemed the Vedas, which are the source of human civilization. Human civilization is based on the qualitative divisions of social order, namely the intelligent class, the martial class, the productive class and the laborer class. The Vedas provide the right direction for advancing in spiritual cultivation and economic development and regulating the principle of sense gratification, so that ultimately one may be liberated from material contamination to his real state of spiritual identification (ahaṁ brahmāsmi). As long as one is in the contamination of material existence, one changes bodies from the aquatics up to the position of Brahmā, but the human form of life is the highest perfectional life in the material world. The Vedas give directions by which to elevate oneself in the next life. The Vedas are the mother for such instructions, and the brāhmaṇas, or persons who are in knowledge of the Vedas, are the father.
