首楞嚴義疏注經 5.361

5.361

毘舍浮，云遍一切自在。平治路地，待佛經過，佛以自證法門開示，令平心地，一切皆平者，心為萬法所依，平等含育，長養一切，故名為地。若能平等性觀，與此相應，則一切法無不平等，自在無礙，由是佛名一切自在耳。

Viśvabhū means 'Pervasive Mastery in All'. Leveling the road and ground while awaiting the Buddha's passing, the Buddha instructed him with his own realized Dharma-door, telling him to level the ground of the mind, and everything would be level. The mind is that upon which the myriad dharmas depend; it equably holds, nurtures, and nourishes everything, hence it is called 'ground'. If one can practice the contemplation of the nature of equality and accord with this, then all dharmas will be none other than equal, masterly and unobstructed; therefore that Buddha is named 'Mastery in All'.
