金師子章雲間類解 1.80

始，初也。《大品》云「空是大乘之初門。」此教有二：一始教，亦名分教。今但標始教者，以《深密》第二、第三時教，同許定性無性俱不成佛，故今合之唯言始教耳。

'Initial' means beginning. The Pañcaviṃśatisāhasrikā states: 'Emptiness is the initial gate of the Great Vehicle.' This teaching has two aspects: first, the initial teaching, also named the fractional teaching. Here only the initial teaching is marked because the teachings of the second and third periods in the Sandhinirmocana alike allow that both those with determinate nature and those without nature do not attain buddhahood; hence they are combined here and only termed the initial teaching.
