When a sight comes before the eyes, a sound to the ears or a smell to the nose, there is no choosing involved here in terms of seeing, hearing or smelling. The seeing, hearing & smelling occur automatically, without choosing.
Similarly, when the mind is actually getting enlightened by experiencing the truth, it is not involved in choosing.
The mind may choose to establish itself in the path, that is, choose to develop concentration. However, the path is only the path & not the destination.
Developing & establishing concentration is similar to removing dust from the eyes, wax from the ears or mucus from the nose.
When the concentration is complete, i.e., when the mind is lucidly clear, the enlightenment occurs without any choosing.
