阿彌陀經疏 1.145

1.145

經曰：「微妙香潔」，次釋第四香氣也。《清淨覺經》云：其彼華香八方上下最勝無比，聞其香氣無不適悅。

The sūtra says: "Subtle, wondrous, fragrant, and clean." Next, this explains the fourth: the fragrance. The Pure and Clean Enlightenment Sūtra states: the fragrance of those flowers is supreme and matchless in the eight directions, above, and below; there is no one who smells their fragrance that is not delighted.
