One who has not undergone such garbhādhāna-saṁskāra, or spiritual family planning, is not accepted as being of an actual twice-born family. The garbhādhāna-saṁskāra is followed by other purificatory processes, out of which the sacred thread ceremony is one. This is performed at the time of spiritual initiation. After this particular saṁskāra, one is rightly called twice-born.
