One should not meditate according to one's personal whims. One should know perfectly well from the authoritative sources of scriptures through the transparent medium of a bona fide spiritual master and by proper use of one's trained intelligence for meditating upon the Supersoul dwelling within every living being. This consciousness is firmly developed by a devotee who has rendered loving service unto the Lord by carrying out the orders of the spiritual master. Sri Naradaji contacted bona fide spiritual masters, served them sincerely and got enlightenment rightly. Thus he began to meditate.
