How about a mindfulness meditation book? Here are some options to consider:
1. "Mindfulness: An Eight-Week Plan for Finding Peace in a Frantic World" by Mark Williams and Danny Penman
2. "The Power of Now: A Guide to Spiritual Enlightenment" by Eckhart Tolle
3. "10% Happier: How I Tamed the Voice in My Head, Reduced Stress Without Losing My Edge, and Found Self-Help That Actually Works" by Dan Harris
4. "The Miracle of Mindfulness: An Introduction to the Practice of Meditation" by Thich Nhat Hanh
Another idea is a meditation cushion, which can enhance the meditation experience. You could also consider a meditation timer or a CD with guided meditations.
