When you wish to search after the secret of life, the learning which one calls learning, that is the first thing to unlearn. No doubt it is something which is a difficult thing for everyone to understand. And yet when we read the life of Rumi, a great Teacher, and his Teacher, Shams-i-Tabriz, the first lesson he gave to Rumi was that: unlearn all that you have learnt. And now you may ask me: is this unlearning forgetting all that one learns? Not at all. It is not necessary. This unlearning is: to be able to say with reason, with logic, the contrary to what one knows. When you are accustomed to say: this is wrong, this is right, this is good, and this is bad, this is great and this is small, and this is higher and this is lower, this is spiritual and this is material, this is up and this is down, and this is before and this is behind, if you can use the opposite words for each with reason and with logic, naturally you have unlearn what you have once learnt.
