首楞嚴義疏注經 9.219

9.219

初至賓主者，明境發所由也。主肝曰魂，主肺曰魄，主脾為意，主腎為志，主心為精神，根身種子皆為第八所執受故。定心精究，內外唯空，遂令五內主神無所依附，流出于外迭互相依，故云互為賓主。忽於下四句正明發相，此則先所修習聞慧種子，定力所激，禪中發生，遂寄神魂現於說法也。此名下，結判邪正。離合即賓主也，或離心主而賓於肝等。餘如文。

From the beginning up to "become guests and hosts for each other" explains the reason why the state arises. What governs the liver is called the ethereal soul (hun); what governs the lungs is called the corporeal soul (po); what governs the spleen is the intention (yi); what governs the kidneys is the will (zhi); what governs the heart is the essence-spirit (jingshen). This is because the sense faculties, physical body, and seeds are all appropriated and sustained by the eighth consciousness. When the concentrated mind investigates profoundly, inside and outside become purely empty, thereby causing the presiding spirits of the five viscera to lose what they depend on; flowing outward, they alternate in depending on each other, and hence it is said that they "become guests and hosts for each other." The four lines from "suddenly in space" onwards directly explain the manifestation of the state. These are the seeds of hearing-wisdom cultivated previously; stimulated by the power of concentration, they arise within dhyāna, whereupon they rely on the spirits and ethereal souls to manifest as the preaching of the Dharma. From "This is called" onwards, the text concludes by judging between the demonic and the correct. "Separating and uniting" refers precisely to guest and host: either separating from the heart as host and taking the liver as guest, and so forth. The rest is as in the text.
