I mentioned the word 'discipline' above. Krishnmaurti often spoke of the importance of discipline, linking it with the notions of 'freedom' and 'intelligence' (cf wisdom). Here is a short YouTube video in which Krishnamurti refers to discipline as 'the act of learning all the time':
The Apostle Paul wrote, ‘Whatever is true, whatever is right, whatever is pure, whatever is lovely, whatever is of good repute, if there is any excellence and if anything is worthy of praise, let your mind dwell on these things’ (Phil 4:8).
Now, that, also, is wisdom.
