大般若波羅蜜多經般若理趣分述讚 3.219

3.219

讚曰：上明一句一字尚假先因，此明從首至終，故資多行。四事俱羅號為供養，三業虔奉立恭敬名，頂載慇懃復稱尊重，先談不已又名讚歎。殑伽者恒神之名，等者相似，佛數齊均與沙相似。此河之中純沙無石，如今渭水無石唯沙。俱胝者百萬也，那庾多者萬萬也。一顆沙為一俱胝那庾多，佛令供養等八十殑伽沙百萬之萬萬佛，乃能具足聞此深經。不爾，無能具聞深義。以經深理非是小智下愚所知，故假大因。今方修遇，歡哉今者幸遇靈文。

The commentary says: The above clarified that even a single phrase or word still requires prior causes; this clarifies that from beginning to end, one therefore relies on many practices. The four requirements provided together are called 'making offerings'; devout service with the three modes of karma establishes the name 'respect'; bearing upon the crown of the head with earnestness is further called 'venerating'; speaking of it beforehand unceasingly is also called 'praising'. 'Ganges' (Gaṅgā) is the name of the river goddess; 'equal to' means resembling, the number of buddhas being equal and resembling the sands. In this river there is pure sand without stones, just like the Wei River today which has no stones, only sand. A koṭi is ten million, and a nayuta is one hundred million. One grain of sand stands for one koṭi of nayutas; the buddhas require one to have made offerings to buddhas equal to eighty Ganges sands of tens of millions of hundreds of millions, before one can fully hear this profound sūtra. Otherwise, none can fully hear its profound meaning. Because the profound principle of the sūtra is not what inferior wisdom and base fools can know, it therefore requires a great cause. Now we have cultivated and encountered it; how joyful it is that today we fortunately meet these numinous words!
