I am trying to locate a source of a quote. In "China and the Christian Impact" by Jacques Gernet there is a footnote quoting a passage from Zhu Xi (I will provide it below). The bibliographical address for the passage is "Songyuan xue'an, Guoxue jiben edn, II, chapter 12, p. 32". My edition of Songyuan xue'an (宋元学案） is A four volume zhonghuashuju （中华书局). In my version chapter 12 is in the first volume (pp.497-535). Unfortunately I was unable to locate the quote in my edition of songyuan xue'an. I will be greatful for any help.
The quote from Zhu Xi in Gernet's book is: "Every time I look at the trees blossoming with different kinds of flowers lit up by the morning sun, with all the flowers blooming joyously, they seem to me to have a sense of life (shengyi). There is an exploion, a general surge of corollas opening to the sunshine. On the other hand, the dried-up branch with its dead leaves is experiencing a feeling of sadness: that is because its vital energy is gone"
