We are just a bunch of memories and an accumulation of food.This statement that our mind is a bunch of memories and our body an accumulation of food by Indian mystic Sadhguru is so undeniably true. When I ponder upon it I cannot find any other meaning to our physical being. No doubt there is more to us than just physical form but when we observe and see ourselves in physical reality we are nothing more than accumulation of memory and matter.
Whatever there is in our mind is just past memories and experiences. In terms of our body we have grown up by eating food and that food is now us. For the same reason we are always advised to eat good healthy food and same goes for our thoughts.
