v2.c15.29

Those that have undergone the *nirvāṇa-dīkshā* are divided into two classes, the *sādhakas* and the *āchāryas*, and for being called by these names they should once again undergo the ceremony of anointment as *sādhakas* and *āchāryas*. The *sādhakas* are supposed to have attained the eight *siddhis* or powers, beginning with *aṇimā*, so well-known through the *Yōga* system; the *sādhakas* are entitled to observe the *nityakarmas* or daily observances such as bath, *pūjā*, *japa*, *dhyāna* and *hōma*, and *kāmya-karmas* only; whereas, the *āchāryas* are entitled to perform, in addition to these, *naimittika* ceremonies such as performing the *dīkshā* ceremony on others, and *pratishṭhā* ceremony or consecrating images.
