Another piece of Buddhist wisdom that word for word applies to proper practice with ayahuasca. When you are able to detach from your preference, and stay observer of your mind, not only you train yourself for less turbulent ceremony but also for less turbulent life.
And the second part is about how obsession about reaching full potential, healing or any other excessive focus on reaching the goal, rather than on balanced and focused pratice is itself the main obstacle in obtaining that goal, and misses the lightness that already is. Be persisent, be dilligent, but never forget to be kind.
“As you settle the mind in its natural state—which is profoundly different from its habitual, dualistic state of distraction and grasping—you will find that it heals itself and unveils its own inner resources of well-being. Gyatrul Rinpoche told me, “When your mind is settled in its natural state, even if a thousand demons were to rise up to attack you, they could not harm you. And even if a thousand buddhas appeared to you in a vision, you would not need their blessing.”

“ If you’re trying your hardest, you’re trying too hard and you’ll burn out if you persist in that way. By cultivating shamatha with intelligence, perceptiveness, patience, and enthusiasm, none of your mental afflictions will be healed irreversibly. They will still arise from time to time, but the more you advance, the more those afflictions will subside and the greater autonomy you will have from them. The result is increasing emotional balance and equanimity. Your psychological immune system is strengthened, so when events occur that were previously upsetting, you can now deal with them with greater composure. Your mind remains calm and it is not dominated by the passions of craving and hostility. This is a clear indication of heightened sanity.”
