evam vidho brahmacari
vanaprastho yatir grhi
evam vidhah—in this way; brahmacari—whether one is a brahmacari; vanaprasthah—or one is in the vanaprastha-asrama; yatih—or in the sannyasa-asrama; grhi—or in the grhastha-asrama; caran—by practice of self-realization and understanding of the Absolute Truth; vidita-vijnanah—fully conversant with the science of the Absolute Truth; param—the Supreme; brahma—the Absolute Truth; adhigacchati—one can understand.
By practicing in this way, whether one be in the brahmacari-asrama, grhastha-asrama, vanaprastha-asrama or sannyasa-asrama, one must always realize the all-pervading presence of the Supreme Lord, for in this way it is possible to understand the Absolute Truth.
This is the beginning of self-realization. One must first understand how Brahman is present everywhere and how He is acting. This education is called brahma jijnasa and is the real concern of human life. Without such knowledge, one cannot claim to be a human being; rather, he remains in the animal kingdom. As it is said, sa eva go-kharah: [SB 10.84.13] without such knowledge, one is no better than a cow or an ass.
