Once a wise old sage, who was looking for an apprentice, made a profound statement to a gathering of would be apprentices. Whereupon the novices (would be apprentices) nodded their heads in studied and complete agreement. Save two; one who respectfully objected that the statement had not made sense, the other who bluntly admitted that they had not understood the statement. The sage chose them!
If you had truly understood you would have realised that it did not make sense.
