Do: Pray. Offer. Start out small. Pray on the days where you feel like praying, and especially pray on the days where you don’t feel like praying. Find a friend who can assist you with divination. Learn about miasma.
Don’t:
Fear miasma (since it happens to everyone). Stop your practice because you don’t feel like you’re good enough. Stop your practice because you made a mistake.
Mistakes happen; our understanding grows, and we change how we do things.
