In ordinary life in order to accomplish something, you have to develop a desire for it and then maintain as an attachment.
In meditation too, …often we build up tensions in order to remind ourselves of our desire for accomplishing something in meditation when the mind seems to have other plans..
Yet, if you know the laws of the mind, you can let go of the desire, remove the attachment and yet not forget what you want to accomplish…This will require that you learn to put up a program in your mind, which is capable of properly formulating a desire, forgetting and remembering.
With accomplishment in the art of remembering and forgetting, life will become much easier and many sufferings can be avoided
