Try to understand logic behind it not religion. Few snips:-
Many aspects of aquiring/getting knowledge:-
"The knowledge through the medium of the five senses.
The knowledge which is based on the interpretation of signs, the understanding of speech, words, writings, gestures, etc.
Clairvoyance, the transcendental knowledge of corporeal things, occurring without the medium of organs.
Extrasensory perception, the transcendental knowledge of the thoughts of others, occurring without the medium of organs.
Unlimited, absolute, direct Omniscience, perfect and highest form of knowledge and perception."
While other types of knowledge are prone to error on account of delusion, only last one is perfect and free from all errors.There is a direct relationship between Supreme Non-attachment and Omniscience."
