Sui-hsin-hsing Wei (Position of the practice following faith) is the first of the Seven Saintly Positions. The name of this position Sui-hsin-hsing (Skt., śraddhānusārin) is derived from the person with dull faculties (Ch., Tun-ken; Skt., mṛdvindriya). He enters the Path of Vision (Ch., Ju Chien-tao; Skt., niyāmāvakramapa) by his belief in what he is told by others, but not by his own intellect.
Sui-fa-hsing Wei (Position of the practice following the Dharma) is the second of the Seven Saintly Positions. In opposite to the above one, the person with relatively sharp faculties (Ch., Li-ken; Skt., t̄kyṣṇēndriya) achieves this position Sui-fa-hsing (Skt., dharmānusārin), because he enters the Path through his own contemplation of the Four Noble Truths. The first and this second position are at the initial stage of religious path and are referred to as the “Path of Vision” (Ch., Chien-tao; Skt., darśanamārga) (which entails no practice).
