Is it possible to meet an instructor in the astral plane for help?
“Now I go alone, my disciples, You too, go now, alone. Thus I want it. Go away from me and resist Zarathustra! And even better: be ashamed of him! Perhaps he deceived you. The man of knowledge must not only love his enemies, he must be able to hate his friends. One repays a teacher badly if one always remains nothing but a student. And why do you not want to pluck at my wreath? You revere me; but what if your reverence tumbles one day? Beware lest a statue slay you. You say that you believe in Zarathustra? But what matters Zarathustra? You are my believers—but what matter all believers? You have not yet sought yourselves; and you found me. Thus do all believers; therefore all faith amounts to so little. Now I bid you lose me and find yourselves; and only when you have all denied me will I return to you.” -Thus Spoke ZarathustraIt is true: you can receive help from instructors, but the best help is always a Master of Major Mysteries who has fully annihilated the ego. The chapter I referenced from The Zodiacal Course by our Sheikh and teacher, Samael Aun Weor, explains this very well. Study and meditate upon the contents of that link!
