Dear List: At the end of his article Sex and Yoga, J.M. (then J.L.) Masson quotes this shloka: tyaja dharmamadharmaM ca tyaja satyamasatyaM vaa satyaasatye ubhe tyaktvaa yena tyajasi tattyaja and gives no reference for it, presumably because it is so famous that it needs none. But I need one. Where is it from? P. Ernest
