If we are unable to investigate even our own mind and state of being, how can we possibly know anything about the state of being of another person? Certainly, the internet is not a reliable or trustworthy means of investigating much of anything, especially when the fate of your soul is at stake.
Furthermore, even if someone were to display spiritual powers, what does that even mean? Even demons have spiritual powers. So what?
Spiritual powers are very easy to develop, but ultimately mean nothing, because powers do not liberate the consciousness from karma.
We do not covet or value powers, or use them as a measure of progress. For us, progress is measured by ethical and psychological character. That is, we esteem a person for displaying great love for others, wisdom, diligence, chastity, altruism, generosity, etc.
Much of the book
The Major Mysteries addresses these themes:
Regrettably, our human “I” wants to appear everywhere, our human “I” wants to be applauded and admired by everyone; the human “I” lets his hair and beard grow and wears strange clothes in order to appear publicly on the streets, so that the naive can call him master, elder brother, etc., thereafter, like a harlot the human “I” gets publicly undressed in order to show off his powers, qualities, and lineage.
Yes, the human “I’s” “love the uppermost rooms at feasts, and the chief seats in the synagogues, and greetings in the markets, and to be called of men, Master, Master.” - Matthew 23: 6, 7
The human “I” has no humility; he boasts about everything, he swaggers about everything, he shows off everything without any modesty whatsoever. The human “I” is an actor who works in order to be applauded and admired by others.
Vanity of vanities, saith the Preacher, vanity of vanities; all is vanity. - Ecclesiastes 1: 2
The human “I” is filled with jealousy; this is why the human “I” loves to be disguised with the cloak of Aristippus. Tradition tells how Aristippus, a great Greek philosopher, wanting to show his wisdom and humility, garbed himself with an old cloak, full of patches and holes. Thus, grasping the staff of philosophy and filled with a great humility, Aristippus walked through the streets of Athens, and in this fashion Aristippus arrived at the home of Socrates.
When Socrates saw him coming, he exclaimed, “Oh, Aristippus, I see thy vanity through the holes in thy cloak.”
The human “I” knows how to conceal anger within recipients made of ice; yes, within cold recipients filled with beauty and ineffable perfume, the human “I” hides the fire of anger. This is how when driven by jealousy he declares that he is prudent and he states that his anger is just confusion and stress, etc. Indeed, crime is hidden within the incense of prayer.
The authentic Master never boasts of being a Master. The true Master is unknown. He dresses like any ordinary citizen and goes around anonymous and unknown.
Therefore, in order for the Being to be born in us, the “I” must completely die. The Being is what is, what has been and what shall always be. The Being is the life that throbs in each atom, the Most Exalted within us. The Being is impersonal; it is the Innermost, the Most Exalted within. The Being is beyond desire, beyond the mind, beyond the will, even beyond consciousness. - http://gnosticteachings.org/books-by-samael-aun-weor/the-major-mysteries.html
Finally, if in this questioning you are seeking someone to follow, we recommend you learn how to follow your own inner Being. Do not rely on so-called masters or teachers in the physical world. Only your Being can guide you to liberation.
