Examples a.) of time-denoting puraḥ etc. Çâk. VII happiness is said to be the consequence of the favour of mighty persons tava prasādasya puras tu saṃpadaḥ (but your favour is anticipated by happiness), Mhbh. 1, 232, 1 purataḥ kṛcchrakālasya dhīmāñ jāgarti pūruṣaḥ; — b.) of prāk and pūrvam. Çâk. V prāgantarikṣagamanāt svam apatyajātam anyair dvijaiḥ; Ragh. 12, 35 abhigamanāt pūrvam (before approaching).
