If we are proceeding by separating the guru/student relationship from the Guru Yoga meditation, here is a partial description of the GY practice:
More Ringu Tulku quotes
You can visualize yourself like her even if you are a tall macho muscled man with beard and all! In the Vajrayana practices, we often visualize ourselves as different deities, sometimes male, sometimes female, sometimes very beautiful, and sometimes quite ugly. They can be tall or very short, black, blue, red or any color, with two arms or many. I think it is a way of training our mind, of not being completely attached and clinging to our sense of reality, of identity as being this or that.
A corpse is usually considered as something not so nice, but here we are standing on a human corpse. The corpse is lying on a sun disk on top of a red lotus. We are holding a curved knife and a skull cup from which we are about to drink. This is also an exercise in diminishing our strong propensity to label things as good or bad, clean or dirty. In this visualization, bad things are not bad, good things are not good. We try to cut of from those concepts of dirty, bad, negative, not wanted, good, very nice, wanted and so forth.
It is also sometimes explained that if, in the beginning, we just see ourselves as usual, we keep our strong attachment to our deluded way of seeing everything, whereas if we visualize ourselves as a yidam, a purer level of being, it may be easier to develop a new way of seeing, which might help us get the understanding. When we visualize ourselves as a deity, we do not only try to look different, we also try to feel as an enlightened being, as whatever his or her form may be.
It is enough to feel the presence of these people, all the enlightened beings, all the masters of the lineage, and not only of the lineage of our own tradition but all the other lineages, whatever they may be, throughout space, throughout the universe, all of them. We should feel that they are there, feel their benevolence, their trustworthiness and willingness to help.
As I explained before, devotion is the very positive, warm, trusting feeling we develop towards a really good friend whose sole concern and motivation is our own good, and who has the capacity to help and benefit us.
Here we are surrounded by enlightened beings, completely good, with no selfish motives, only wanting to help all sentient beings. Moreover, they not only have the willingness to help but the power to do so, therefore, we feel protected, loved, cared for. That feeling is the most important. When we have developed it, we have completed the purpose of the visualization.
So, having separated the interpersonal relationship with the guru from the GY, we can do this practice without the fear and limitation of having to trust an actual flesh and blood human being. Thus we can cultivate ourselves in this direction freely.
I support Mingyur R and HHDL in their positions against Lama abuse.
