It is indeed amazing how a Guru can show the clearest and easiest path to Liberation and yet the seeker (or more appropriately 'the ego') will refuse to see the clarity and simplicity of the message. Contrary to what many of you readers may be thinking, it is not necessary to blindly accept what the Guru is saying. Instead, it is imperative that you must question and analyze the teachings and sayings of the Guru and come to your own conclusion. This process is called inquiry into the Self. However, it is this author's opinion that complete and unquestioned faith in the Guru is the essential ingredient in the successful culmination of one's effort to attain liberation. Nothing could be simpler than SEEING one's own Self.
As Bhagavan Ramana Maharshi said - " When rightly considered, nothing will be more wonderful and laughable than one's toiling very much through some sadhana(spiritual practice) to attain Self in the same manner as one toils to attain other objects, even though one really ever remains as the non-dual Self".
If one listens carefully to the above (Shravana) and then cogitates over this simple teaching (Manana) and meditates on the nature of one's own Self or internalizes one's conceptual understanding as a fact (Nidhidhyasana), then one merges with the Guru, which is Self Realization or Liberation. Ramana Maharishi started out by clearly saying "when rightly considered....." and hence He implies inquiry and questioning the very methodology i.e. sadhana or practice, by the seeker. However, upon careful and complete inquiry, there is no doubt that one will arrive at the conclusion that it is utterly ridiculous for one to perform any kind of sadhana to BE what one already IS!! There is only ONE without a second and hence the concept of being any thing other than THAT ONE is nothing other than a concept. A concept is not real. Only THAT is the Reality. Why don't you investigate and SEE for your self?
