14.44

剎那後成過者，此明別解脫無表初剎那後亦成過去，法後得故，成過去也。由此初念唯成現世。若第二念通成二世，無法前得，不成未來。問：「何故無法前得？」答：「不隨心色勢微劣，故無法前得。」

'After that moment, one possesses the past': this explains that after the initial moment of the avijñapti of prātimokṣa, one also possesses the past; because of acquisition posterior to the dharma (paścātprāpti), one possesses the past. Consequently, in the initial moment, one possesses only the present time. In the second moment and onward, one possesses both times; there is no acquisition prior to the dharma (pūrvaprāpti), so one does not possess the future. Question: 'Why is there no acquisition prior to the dharma?' Answer: 'Matter that does not conform to the mind has weak power, so it has no acquisition prior to the dharma.'
