Disclaimer: I’m not a doctor!
But from my experience going to some, generally we would have some problem, like say a stomach ache. We don’t go to a plumber for this, although a leaky gut might need some plumbing of another kind. The doctor would have to be a general physician at first and then maybe a gastroenterologist. And the all important medicine? Some specific tablet or syrup that only the doctor can prescribe.
Our life’s problems are no different.
What is the illness? Samsara, aka our dependence on external factors for attaining and maintaining happiness. Who’s the doctor? This one is easy, the Guru of course! And the medicine? Scriptures, spirituality, devotion, God… take your pick.
