首楞嚴義疏注經 6.211

6.211

藥王、藥上因嘗眾味，了味無生，非即身心，非離身心。由味覺明，位登菩薩。今云：味性本無，待根方覺，無根無味，故非圓通。味時者，嘗時也。

Bhaiṣajyarāja and Bhaiṣajyasamudgata, through tasting many flavours, understood that taste has no arising, is neither identical to body and mind nor separate from body and mind. Through the illumination of awareness of taste, they ascended to the rank of bodhisattva. Here it is said: the nature of taste is fundamentally nonexistent, awaiting the faculty before it is perceived; with no faculty, there is no taste; therefore it is not perfect penetration. 'When tasting' means the time of savouring.
