In Buddhism, there are four varga in Sanskrit, hereafter four groups.
They are the two groups of monastics, bhiksu and bhiksuni or monks
and nuns, and two groups of householders, upasaka and upasika or
male and female devotees. Matrimony is prohibited for the two groups
of monastics, whilst it is systemically practiced for the two groups of
householders, but with the preceptive order against sexual misconduct
beyond the marital bond.
Celibacy, neither approved nor disapproved in Buddhism, is basically
a personal issue. For individuals with lofty aspirations or religious
commitments necessitating a lifetime of dedication, celibacy works
splendidly. On the other hand, for individuals seeking lifelong companionship,
marriage, which is all about rational, normal coexistence
between the spouses, works equally well.
