1.58

若於方所現等者。於方所者。謂現前色不離方處故。所現骨鎖等者。即觀行者所觀同類影像諸色。形顯者。形謂形色。顯謂顯色。如是總名方所示現。

Regarding 'manifesting with respect to spatial location', and so forth: 'with respect to spatial location' means that present form is not separate from a spatial location. 'The skeletons and so forth that are manifested' are the various forms of homogenous mental images contemplated by the practitioner. 'Shape and color': 'shape' means shape-form; 'color' means color-form. These are collectively called 'manifestation in a spatial location'.
