Is Pureland not a fantastic construction of a deluded mind? If your response is no, how do you know it isn't?
a)No. b)Because the Arya Sangha teaches them.
I am my own teacher. Buddhism isn't too big in my part of Brazil so my options in this department are very limited. I'm a trial and error kinda guy and usually figure things out for myself and excel without formal training, whether it's development via spiritual practices, artistic, creative, and professional skills, or whatever else it may be that I develop an interest or need for. I currently practice theravada meditation practices, tao meditation/energy practices, and dream yoga/lucid dreaming and out of body/astral projection. I've been involved in the ladder practices for half of my life, but only seriously got into Buddhist meditation not even a few months ago, as I have recently solidified my desire and efforts to make serious spiritual progress along the lines of the Buddhist path. I now consider the out of body experiences to simply be icing on the cake, although my experiences thus far in higher nonphysical dimensions have demonstrated serious potential for attaining spiritual insights and knowledge.
Okay. But to practice Vajrayana techniques you REALLY need the guidance of a qualified and realised teacher. 100% necessary because there are so many pitfalls on the path. There are many very good teachers regularly giving profound teachings online now days. Take advantage of them.
Three that I can think of off the top of my head: Namkhai Norbu, Garchen Rinpoche, Tenzin Wangyal. I am sure that people here can tell you of more. One of my Kagyu teachers travels regularly to Brazil to support a small sangha (with a Lama) based there. If you wish I can find out where they are (yes, I know Brazil is a large country, but you never know your karma, they might be right next door to you
Oh, careful of certain Tibetan cult groups, there are some well established ones in Brazil.
PS So that we don't drag this topic even further off topic maybe people can contact Vince via PM with more information.
