仁王經疏 3.71

3.71

釋曰：第二、王自得益。謂王自證虛空等定，聞法悟解，此即法空觀也。由此定力，至斑足所。

Explanation: Second, the king himself obtains benefits. It means that the king himself realized the space-like samādhi and, hearing the Dharma, awakened and understood; this is the contemplation of the emptiness of dharmas (dharma-śūnyatā). By the power of this samādhi, he went to Kalmāṣapāda's dwelling.
