Once I had an opportunity to talk with Chogyam Trungpa, Rinpoche, about the fact that I was not able to do my practice properly. I had just started the vajrayana practices and I was supposed to be visualizing. I couldn't visualize anything. I tried and tried but there was just nothing at all; I felt like a fraud doing the practice because it didn't feel natural to me. (...). So he encouraged me by saying that as long as you have these kinds of doubts, your practice will be good.
