So mahayoga vigyana describes the qualities of a guru. It is written so a disciple can find a true Guru
I would like to add a few things to it. Qualities that should NOT BE PRESENT
A guru who has a set fee
A guru who has camps ( shows that he is interested in money )
A Guru who quotes physiology, modern day science research etc. Experience of spirit is rare but far exceeds any science ever. Jesus rubbed dirt in a blind woman’s eye and healed her. Which medical science can explain that
A guru surrounded by a many disciples. Why? those worthy of the highest experience are far and few
Generally a guru does not entertain speeches to the masses. There are a few exceptions like shukdev and Gyaneshwar. In modern times a few came out but only because they were forced. Vivekananda had no desire to give mass talks but Ramkrishna his guru blocked him from higher experiences until he fulfilled the Divine mission. Yogananda similarly had a mission to be fulfilled for Babaji. However they gave a lot of talks but only had a very limited number of disciples. ( Just because you think they are your Guru does not make them your Guru. Something very unique, something Divine happens with the blessings of a Guru. The guru has to be living in a physical body for that to happen. When that happens the disciple has no need for any book, scriptures, any other teacher or Guru. Does not need blogs. So. Long as you find the need to read books, blogs or keep searching for a Guru, there is something laacking. All searches end when the Guru connects with a disciple. It’s like a dead stop. All that is needed is inner meditation. Having said that there are weaker disciples who cannot fully absorb the gift from a guru and takes decades to move forward )
So long as you measure the level of a guru by popularity or number of disciples or volumes of books written or his oratory skill, you will never find a true Guru. Those things that mean a lot to you are trash to an enlightened person. God is not a promotional subject or popularity contest. God or spirituality is about peace and immense inner satisfaction that all other searches end. Instantly. Literally. You say I don’t want anything the world offers.
Such people are rare. Now reflect on this. See where you are. Don’t lose hope. Eventually the desire for truth will win and the doors open. You will seek the company of these rare people. Nothing else will ever satisfy you again
