Absolute Faith
Have an open mind to accept that God is capable of coming into any body

Have an open mind to accept that God is capable of coming into any body. Did not Lord Narasimha thunder forth from a pillar for the sake of his child-devotee Prahalada?
If God can present Himself thus from brick and mortar, a non-organic substance, then how can He not present Himself in this organic substance called Siva Shankar Baba, a living legend who can see, hear, smell, talk and sense. You should be a Prahalada to get Perumal out of me. Whether I am Perumal or not is immaterial.
Become a Prahalada, then you will be able to perceive God come through me, He can come through this pillar, HE will also come through this plantain tree. You should inculcate, imbibe that faith.
Anyone who contains the divine qualities of love, selfless sacrifice, limitless compassion, truth, etc, can be termed divine.
