But even they are external to the seedless (Samadhi).
In plain words: Yet even these three are outer steps compared to the highest, 'seedless' Samadhi. In that state no seeds of future desire or rebirth remain. Special powers are not the final goal.
Compared with that seedless Samadhi, therefore, even these are external. We have not yet reached the real Samadhi, the highest, but a lower stage, in which this universe still exists as we see it, and in which are all these powers.
Namaste.
