Contexte: People who practice mental concentration may inhibit the True Mind within themselves by being dependent on sensory perceptions, coarse states of mind, and restricted breathing. Before achieving mental purity, [such people may undertake] the constant practices of concentrating the mind and viewing the mind. Although they do so during all their activities, [such people] cannot achieve [mental] clarity and purity, nor illumine that mind which is the sources of all dharmas.
