Carya means
Sri Caitanya-caritamrta
CC Madhya-lila
The word puraḥ means "before," and caryā means "activities." Due to the necessity of these activities, we do not immediately initiate disciples in the International Society for Krishna Consciousness. For six months, a candidate for initiation must first attend ārati and classes in the śāstras, practice the regulative principles and associate with other devotees. When one is actually advanced in the puraścaryā-vidhi, he is recommended by the local temple president for initiation. It is not that anyone can be suddenly initiated without meeting the requirements. When one is further advanced by chanting the Hare Kṛṣṇa mantra sixteen rounds daily, following the regulative principles and attending classes, he receives the sacred thread (brahminical recognition) after the second six months.
