The Buddha taught us this.
“The next time it manifests, we will receive it the same way; we will care for it the same way with the energy if mindfulness, and then it will return to the depths, weaker still. It loses energy every time it is embraced by the energy of mindfulness, which is really a mother.
The door is already open; mental formations can now flow freely. And if you practice that for a few weeks, the symptoms of mental illness will disappear. This is because you are now in a situation where you have good circulation in your psyche. That is why Buddha taught us to invite fear into our mindful consciousness and care for it every day.
There is no battle between good and evil, positive and negative; there is only the care given by the big brother to the little brother. In Buddhist meditation, we observe, we act in a nondualistic fashion, and thus the waste materials if the conscious mind can always be transformed into flowers of compassion, love, and peace. Our consciousness is a living thing, something organic in nature. There are always waste materials and flowers in us. The gardener who is familiar with organic gardening is constantly on the alert to save the waste materials because he knows how to transform them into compost and then transform that compost into flowers and vegetables. So be grateful for your pains, be grateful for suffering – you will need them.”
