Between conception and cremation, a Hindu was to have his lifespan punctuated by a total of 16 major samskaras (바카라rites of passage바카라 or 바카라initiation ceremonies바카라) out of which the upanayana samskara is one of the few that still survive in practice. It was primarily meant as an enabler for the study of the Vedas and performance of Vedic sacrifices. Therefore, it is available only to male members from the first three tiers of classical Hindu society, namely, Brahmins, Kshatriyas, and Vaishyas, who can be approximately (if somewhat inaccurately) understood as the intellector class, the warrior class, and the mercantile class respectively. However, there are clear statements in Hindu religious literature to the effect that 바카라in earlier times바카라, the initiation was extended to femÂales also from these classes, and there are hints pointing to the ceremony being inclusive enough to cover members from the fourth class as well. However, it is unambiguous that males from the first three classes are entitled to upanayana. It is the 바카라second birth바카라, which makes them dvi-ja, that is, 바카라twice-born바카라.
