How do you know if you are progressing spiritually? What are keys which when recognized tell that you have become something more advanced?
Progression is something that many spiritual seekers get locked up in. Because they may or may not see either immediate of even advanced progression they begin to doubt (technique, book, guru, or even God).
By contiuning in the way of that which was taught (most especially if it was through a system that works for majority of individuals or if it was from a god realized guru) on in time should be seeing results.
There are three things which most beginners will begin to see.
1. Bliss. This could be financial, materialistic, peace, things falling into place. Better relationships, less burdens, knowledge or even health.
2. More Samadhi. Although self explanatory, time could free up for spiritual work. Time in samadhi and depth of samadhi may all increase.
3. Siddhis. Minor and then minor siddhis or spiritual powers (things like clairvoyance, clairaudience or sentience. Telepathy, manifesting, teleporting, levitating, or even eventually omnipotency and omniscience.
Because these things take time and occasionally are hard to determine if they have occured, one should continue or even make more drastic determination to progress. This without attachments to results. This is the way of the master.
