The mind that is empty of all its past

So you must ask this question, put this question to yourself, whether your mind can be empty of all its past and yet retain the technological knowledge, your engineering knowledge, your linguistic knowledge, the memory of all that, and yet function from a mind that is completely empty. The emptying of that mind comes  about naturally, sweetly without bidding, when you understand yourself, when you understand what you are. What you are is the memory, bundle of memories, experiences, thoughts. When you understand that, look at it, observe it; and when you observe it, see in that observation that there is no duality between the observer and the observed; then when you see that, you will see that your mind can be completely empty, attentive, and in that attention you can act wholly, without any fragmentation.
