“As Shantideva says, you have been sick for a long time with the illness of the afflictions such as attachment–an illness that is long-lasting, intractable, and causes strong suffering…. Sick persons know that their illness cannot be cured without taking the medicine prescribed by the doctor. They then take the medicine. Likewise, earnestly engage in practice after you have seen that you cannot vanquish such afflictions as attachment without putting into practice the instructions given by the instructor. Do not devote yourself to just piling up words in great numbers without engaging in practice.”
