Vaheguru ji Ka Khalsa
Vaheguru ji Ki Fateh ji
I don`t think it`s wise to neccesarily equate tantra with black magic.. The thing with tantra is, it is like ``fire``. ``Fire`` can be used to bring light during the dark, or it can be used to destroy. All I know though is, that we as Sikhs should only recite Sri Gurbani Sahib ji from our Sri Satguru Sahib ji since it is not kachi. Sarbat da bhalla.
