On the pure mind – a reflection of the past lives – ours and family and friends- falls very clearly
Do you know your past? The past of your family ? The karmas of others ?
We can always make a claim. Or assume our saint knows it but truth is most of the people know NOTHING! This is specially true for the so called guru
It is not important that they know it but it is a natural gift for a Guru
Where do you stand in purity ?
