四教義 10.25

10.25

次無礙三昧破空處有者，此處得出色籠，飄颺無礙，未是三諦三昧之無礙，礙見思礙、塵沙礙、無明等礙，菩薩為修三諦三昧破是諸礙，故名無礙三昧。

Next, the unobstructed samādhi destroys existence in the base of empty space. Here one escapes the cage of form and drifts without obstruction, yet this is not the unobstructedness of the samādhi of the three truths: it is obstructed by the obstruction of views and thoughts, the obstruction of dust-like [delusions], the obstruction of nescience, and so forth. In order to cultivate the samādhi of the three truths and destroy these obstructions, the bodhisattva calls it the unobstructed samādhi.
