Sensei letters
Rare letters from Kata about your practice, written when something in your practice has changed. You can’t ask for one; you earn it.
Never in your first 30 active days, never two within 45 days, and at most 5 a year. When one arrives, Today shows A letter is waiting for you.
Open a letter from Today or the bell. All of them stay on your Profile, under Letters.
When a phase ends, it becomes a chapter on your Profile, so the story of your practice stays in one place.
Your first letter comes on every plan. Later letters are part of Kata Plus and Kata Unlimited. A letter you received stays yours to read.
