On this day, I think Dr. Surya was sharing how wonderfully specific the memories of some people are: he illustrated this with an anecdote about a close friend of his, a famous Neurosurgeon, who remembered to buy a specific pencil for his little son although he was always so busy.
He is probably giving us a clue about how to get what we want (Law of Attraction?)from what I have jotted in this page in the diary:
Want scissors? First talk to scissors.
These things are not so much to be discussed as practiced.
