About “tantra practitioners” who employ sex as “the ultimate means” in their “tantra”:

“Those who have not been initiated (adikshita), who deny mudras and mantras, who have not done japa and puja, should not use Kula-tattvas (here panchamakara, i.e. meat, wine, fish, roasted grains, sex). Using them like this will lead the sadhaka to the hell”.

“There are a lot of people who, relying on their opinion, reject the tradition of spiritual transmission and, following false teachings, engage merely in imitation and distortion of Kula-dharma.”

“Thus, if merely by consuming wine one could achieve siddhis, then all unworthy people, who enjoy in heavy drinking, should have achieved siddhis. If merely by consuming meat one could attain spiritual purity, then all meat-eaters should have reached sainthood. If mere sexual pleasure with one’s partner could bring to Liberation, then all living beings should have reached it through the attachment to their partners”.
