The moment you turn thirteen or fourteen, lust arises on its own. That’s what you experience without any effort or discipline, correct? You don’t require to be disciplined or determined for your pubic hair to grow or your periods to start. Stuff just flows on its own!
So, don’t say that wisdom too will start flowing in your mind on its own. That won’t happen. Wisdom and all higher order things in life will never come on their own. What is it that you experience on your own? You only experience hunger, sleep, lust.
