A Vaisnava is immediately purified, provided he follows the rules and regulations of his bona fide spiritual master. It is not necessary that the rules and regulations followed in India be exactly the same as those in Europe, America and other Western countries. Simply imitating without effect is called niyamagraha. Not following the regulative principles but instead living extravagantly is also called niyamagraha. The word niyama means "regulative principles," and agraha means "eagerness." The word agraha means "not to accept." We should not follow regulative principles without an effect, nor should we fail to accept the regulative principles. What is required is a special technique according to country, time and candidate. Without the sanction of the spiritual master, we should not try to imitate. This principle is recommended here: suska-vairagya-jnana saba nisedhila. This is Sri Caitanya Mahaprabhu's liberal demonstration of the bhakti cult. We should not introduce anything whimsically, without the sanction of the bona fide spiritual master. In this connection, Srila Bhaktisiddhanta Sarasvati Thakura comments on these points by quoting two verses by Sri Rupa Gosvami (Bhakti-rasamrta-sindhu 1.2.255-256).
