One of the biggest error I made in mediation is thinking once I have a Guru and shakti is awakened life is a path of roses
Also thinking that from now on I will have multitude of spirtual experiences every day and my personality will change!
Nothing of farther from the truth
Problems in life multiply
Your patience is tested to see can you wait for experiences
My personality took decades for a slight change
So best is if you change yourself first. There is much home cleaning to be done while you wait for a Guru
99% of the people will still lose the path even after having a perfect Guru. Why? Home cleaning was not done
