As the topic suggests, I was curious as to what the division is between the two. Of course I know that an empowerment is necessary to engage in each individual practice but having said that, let's say for practices like Manjushri, Chenrezig, etc., that are normally done as a front visualization, when one receives the specific empowerment is it common (or even more beneficial) to do self visualization as that particular deity? I know for practices related to the higher tantra's (Annuyoga/Ati Yoga) the sadhana's are pretty specific in these cases. But what about some of these more common lower tantra practices?
Of course I prefer just a general discussion and nothing too specific that is not appropriate here.
Often the advice is to "ask your teacher" and I will do that in the next while when I see him, but in the meantime I thought I would ask here.
As an aside, As i feel I have a connection to Cherezig, I was curious if most practices related are from the lower tantra's, or are there some that are not?
Thanks for the input.
