Conclusion

As long as we are in (“Dubidha”) doubts and religious illusions we can’t make much progress on the spiritual path.  So at the end of the day please make a self judgment and find out if you are doing whatever  Guru’s divine word wisdom (“Gurbani”) tells you to do or you are just following the traditions that are prevalent in the society, are you really working according to  Guru’s divine word wisdom (“Gurbani”) and trying to follow the Guru’s divine word wisdom (“Gurbani”), by doing so you will for sure find an answer to the reasons why is your spiritual progress not happening and then you will be able to take corrective actions. Self-evaluation is very important and should be a continuous feature of your daily spiritual chores. Once you are relieved of these delusions & illusions of religion (“Dharam Key Bharams”) your spiritual progress will reach its heights.
