It is said that before the Buddha attained Enlightenment, he leant and practiced meditations from different Hindu gurus, and attained some meditative stages. Do you know what is the final stage of meditation he attainted at that time? Is it the Cessation of perception-and -feeling (sa~n~naa-vedayita-nirodha) or the Ream of neither-perception-nor-non-perception (n'eva sa~n~naa-naasa~n~naayatana)? According to what Pali text (s) we know this?
