Ten affirmations before surgery, for the night before and the morning of — steady words for the waiting, and for trusting your body to heal.

The hardest part of surgery is rarely the surgery. It is the waiting: the fasting, the gown, the corridor, the hours when there is nothing left to organise and nothing to do but think.
These ten affirmations are for that stretch. They do not promise an outcome, because nobody can. They point at the two things that are true either way — your body knows how to heal, and you are in the hands of people who do this every day.
The night before, use the longer lines. Read them slowly, once, and let them be the last thing you look at instead of a search engine. Reading about your procedure at midnight has never once helped anybody sleep.
The morning of, pick one line and keep it. You will be repeating it in a waiting room, possibly to a ceiling tile, possibly while someone finds a vein. Short is better. Saying it as they count you down is fine too.

1. “My body is ready to heal.”

2. “I believe in my body's innate ability to heal all wounds: physical, emotional, and spiritual.”

3. “May I feel healed and at peace.”

4. “I trust that my body is here to help me, not hurt me.”

5. “I have faith in my body's ability to heal itself.”

6. “I accept and allow my body to heal and improve.”

7. “I am thankful for my body's ability to heal.”

8. “I am surrounded by the support of my family and friends while I heal.”

9. “I am surrounded by love and support during my recovery.”

10. “I am safe and surrounded by support.”
One short line, repeated on a slow exhale — "my body is ready to heal" — works better than trying to think your way calm. The aim is a slower breath, which is also what the anaesthetic team wants from you.
They help with the mood of recovery, which matters more than people expect: the first days after an operation are largely about patience. Follow your surgical team's instructions for everything physical.
Whisper or in your head is fine, and both work. If a family member is with you, having them say the line to you is often steadier than saying it yourself.
That is one of the most common fears, and worth saying out loud to the anaesthetist rather than only to yourself — they answer this question daily and can tell you exactly what you will feel.
