Since the very "I" which seeks the truth and practises the meditation is itself so illusory, it cannot attain what it seeks or even practise with success, unless it also receives help from a higher source. Only two such sources are possible. The first and best is the Overself's direct grace. This must be asked for, begged for, and wept for. The next best is the grace of a master who has himself entered into truth-consciousness.
