妙法蓮華經玄贊 7.546

7.546

贊曰：此顯異名成佛處所。阿閦者，無動義，故相用煩惱等一切不動故。「閦」音初六反。若齊作「珿」，直貌作「矗」，廉謹狀作「齪」，不知「閦」字所出。「須彌頂」極尊高故。「師子音」示無畏故。「師子相」示降魔怨故。

The Commentary says: This reveals their different names and places of attaining buddhahood. "Akṣobhya" means unshakeable; because marks, functions, afflictions, and everything else are unshakeable. The pronunciation of chu (閦) is chu-liu fan. If it means level, it is written 珿; if it means an upright appearance, it is written 矗; if it means being narrow and cautious, it is written 齪; the origin of the character 閦 is unknown. "Sumerukūṭa" is because he is supremely exalted. "Siṃhaghosa" indicates fearlessness. "Siṃhadhvaja" indicates subduing the enemies that are Māras.
