This does not need any Tipitaka reference. Not everything needs Tipitaka reference if one would be limited like christians or muslims to scriptures it means one is limited to those scriptures and does not develop any wisdom but just blind faith. Tipitaka is Dhamma which makes people develop wisdom so they can apply it to all sorts of things and come up with the clarity and see things the way they are :)
About the question you asked I will show you examples that can gives you a hint. Let say there is musician who can read the music (notes) but without knowing how to play and instrument and hearing one does not really experience the music one reads. Same with people on the Path, one needs to listen to the Dhamma to truly understand it as musicians needs to learn/listen to music to really understand the notes. :)
