B. Alan Wallace compares the Theravada meditative practice of "attending to the emblem of consciousness" to the practice in Mahamudra and Dzogchen of "maintaining the mind upon non-conceptuality", which is also aimed at focusing on the nature of consciousness. - B. Alan Wallace, The bridge of quiescence: experiencing Tibetan Buddhist meditation. Carus Publishing Company, 1998, page 257.
Anybody know what this "emblem of consciousness" is? I've never heard of this term.
