We say, “Pulling out the weeds we give nourishment to the plant.” We pull the weeds and bury them near the plant to give it nourishment. So even though you have some difficulty in your practice, even though you have some waves while you are sitting, those waves themselves will help you. So you should not be bothered by your mind. You should rather be grateful for the weeds, because eventually they will enrich your practice. If you have some experience of how the weeds in your mind change into mental nourishment, your practice will make remarkable progress. You will feel the progress. You will feel how they change into self-nourishment. Of course it is not so difficult to give some philosophical or psychological interpretation of our practice, but that is not enough. We must have the actual experience of how our weeds change into nourishment.
