According to Tantra-Vachana, Kali-Puja should never be done by the priests. If someone gets it done by a priest, the Mother becomes angry and ruins that person:
purohitam samAniya yadi pujAdi kArayaet/ tasya sarvArtha-hAnih syAt kruddhA bhavati kalikA// (Pranatoshini-Tantra, kanda 5, pari. 6)
Why then do we see priests doing kAli-puja in almost all cases? Is there any scriptural support of this practice?
