FutureHumanDestiny, You asked, "what in your understanding/estimation are they trying to achieve?" --> They are helping us accelerate our progress along the path to enlightenment and then onto nirvana. But they cannot force us in any way, and they cannot step in and make things any easier for us in any way. All they can do is lead by example and answer questions. But one day, when we have made enough progress and we have proven that we are worthy of their direct help, they will start providing us with such direct help. Another factor is karma. If they step in and actively help us make great progress along the path to enlightenment and nirvana, they, not us, will get the corresponding good karma, and they don't want to do this. They want us to accumulate such good karma for ourselves. Another thing about achieving enlightenment and then nirvana is that achieving enlightenment and then nirvana will be the most difficult thing we ever do in this life, past lives, or future lives. Period. (Our achieving achieving enlightenment and then nirvana is going to be a LOT more difficult than most people realize.) The Elder Brothers are not allowed to make this any easier for us. "It is said Maitreya will be the next Buddha. This makes a lot of sense to me. I would not say he will incorporate the consciousness of Jesus, Buddha, etc., but that he will incorporate their teachings." --> "when this is the case, how do you predict that orthodox scholars in those traditions (christian, buddhic, hindu, etc.) will reply to his claims to have incorporated those traditions?" --> Quite frankly, I think a lot of them will reject his teachings. Such is the very nature of Orthodoxy.
