i've been in the esoteric for at least 15 years, at least half of my life (sigh) not including my early experiences.all i can say is there will always be change. as earth moves through the various initiation levels ( as it evolves), it will encounter bigger changes and bigger challenges.
one thing I've learned is that we are always guided by the great ones. for normal aspirants, usually by the inner self and guides / spiritual helpers. the masters will never guide you directly unless you are doing service...unless you are a global leader in service. else it is the ego talking. when one is a high level initiate, only then can a master / hierarchy directly influence him. when an honest and sincere aspirant sees a great figure, say St. Michael or an Indian Saint, in say, a dream., it is just a representation and are usually carried out by spiritual helpers under them. these great souls vibrate at a very high level, mahihirapan ang katawan ng isang tao if they appear. and what for? unless special. but that's the way it happens because of the limitation of an average aspirant's understanding.
there are two teachings. ika nga, oral tradition and written tradition.written ones are in books. they're the safe ones - this is if you can find the good ones as there are a lot of dark teachings out there. the more advanced teachings are given orally because they're dangerous. when you get to this level you'll really see why. it is like being given a truck load of explosives.
the even more advanced teachings are given by telepathy.masters at this level will only deal with you via telepathy. whether physical master sila or ascended master. To meet such a teacher or to reach such a level, you will be limited by the development of your inner senses and your karma. also the very advanced souls do meditations that include the development the higher chakras - the soul chakra at the very least. if you're not doing at least the development of the soul chakra, it is not considered advanced.
Jesus came after Buddha. Buddha predicted 500 years after him a great buddha will arrive. When Jesus arrived, only a few recognized him. Many, including religious leaders, negated him. I'm sure ganun din pag may dumating na teacher na ganun ang caliber.
but there are teachers naman na mataas initation level, but hindi lang sila lumabas tulad ni Buddha, Jesus and Mohammed. you'd just need to find them. (if your karma permits. ) a lot of them walk with us. kailagan lang din talaga ibaba ang ego. else you'll never get to see them. (in a lot of ways it is better to have a physical teacher than an ascended one.) I was fortunate to meet a Himalayan trained teacher when i was in my early teens,15 i think. masasabi ko lang is that the basics have been given. and yun ang dapat hanapin, at i practice. and when the student is ready, the opportunity to meet a master/teacher will be given (depende din sa level). and if the student/soul has a big assignment, the teacher will appear kahit hindi pa sila handa. (ie. Yogananda and Babaji). and they will be the ones who'll take charge of your accelerated development (ie. mr. vivero, ask j. licauco, si Anthony ang pinaka mabilis nadevelop under his wing, at isa sa mga mataas na attain. because the help of the divine. iba pa yung pinatawag siya ng master sa himalayas) Now, kahit mag himalayas pa ang isang tao at makatagpo ng teacher (by pure chance, minsan blessing lang ng master ang kailangan). pauuwiin ka kung hindi ka handa.
