I think 'awareness' comes with spiritual experience. But then again we get 2 extremes- 1st)- We get the learned or scholars that 'insist' because of their spiritual experiences. They then may use such experience to endorse certain areas of gurbani. 2nd)- On the other hand we have the learned and scholars who have spent years studying gurbani and they can help to teach others via adaptive and constructive thinking methods. Professor Sahib is one such respected who I believe has claimed that he NEVER had any such spiritual experience. Where does the common man of a Sikh go to understand ?? Well, I know you can't just sit around waiting for a spiritual experience to happen ! It is only sensible to start by learning from the scholars and sangat that have spent years and years of studying, which they didn't just do for self-gain ! We can't discourage younger and newer Sikhs by telling them that without spiritual experiences, they will have less awareness and understanding. But we should make an effort to understand and learn from the sangat that has.
