I don't think this passage means that one should have no goal and no direction, that one should deny the role of the intellect. There is a place for all this. But I think it means that meditation is an inquiry into the nature of the one mind, where all thoughts originate, whether yours or mine, traditional or not traditional., inefficient or efficient, futile or purpose oriented. What is the state of the mind when it is not identified with any thought? Is it different from silence and is silence different from beauty? When does one best see the great beauty present in nature? Can there be depth and beauty in the field of relationships or must there always be struggle. I think all this is part of meditation and I think meditation proceeds through endless observation and questioning. I may be wrong but this is what I understand Raja Yoga to be.
