Different branches or religions or seekers of the Self when told that the Self cannot be realised through the working of the mind dutifully record this piece of information and continue to collect any other data for their spiritual search.  It is this deluded understanding that would be likely to arrive at a number of principles to be considered as relevant.  Only the deluded could attribute a number to a Unity.  As sincere as these seekers are they need to see that Self attainment comes through surrender.  in the end when finally successful they will have let go of all self power,  they will have let go of all doing and surrendered their being to The Absolute,  because they will not produce or distil intelligence of the Absolute Reality into a form that will be understood by all.  They will,  as said,  have to surrender their self to attain to the Absolute Self which will be known with intellectual certainty,  but verified through the heart,  not words.
