According to Buddhist psychology, there are three stages to the development of a narrative: experience, perfume, and seed. We have the experience, which creates a perfume, an emotional memory. That memory coagulates to form a seed that projects into the future. Our narrative is created and perpetuated by a waterfall of experience, perfume, and seed; experience, perfume, and seed; experience, perfume, and seed. As long as we cling to a narrative, our future is affected by the residue of the past.
Friends are those for whom we carry positive seeds. Our last experience with them left a wonderful perfume that coagulated into a positive seed, so we want to be with them. This tendency keeps our narrative going. For as long as our narrative runs, we experience the present through the past.
But with practice, we begin to notice when we are watering seeds from the past that will condition and limit our future.
