大毘盧遮那成佛經疏 8.29

8.29

右先明一切吉慶所以得生，皆由如來出世。故梵云落吃澁弭（三合），翻為吉祥相，或云具相，亦是嘉慶義、吉祥義、吉慶義、嘉慰義、威德義、好相貌義。當知此名攝一切功德，故會意言之。次句云開敷，亦是覺悟義。水生是蓮花異名。以具如是義故，如來出世多所饒益，故云最初善慶，或云吉慶、或云嘉慶，大體同耳。

The above first explains that the reason all felicitations are able to arise is entirely due to the Tathāgata's appearance in the world. Thus the Sanskrit lakṣmī is translated as 'auspicious mark', or 'endowed with the marks'; it also means 'felicitation', 'auspiciousness', 'good fortune', 'gratulation', 'majestic virtue', and 'fine appearance'. One should know that this name subsumes all merits; hence it is stated through synthesizing the meanings. The next line says 'opening', which also means 'awakening'. 'Water-born' is an alternative name for the lotus. Because it is endowed with such meanings, the Tathāgata's appearance in the world brings abundant benefits; hence it is called 'the initial wholesome felicity', or 'felicitation', or 'good fortune'—their general import is the same.
