Which book talks about spiritual growth?

I’ve been exploring ways to deepen my understanding of myself and the universe, and I’m looking for recommendations on books that focus on spiritual growth. I’ve come across several spiritual empowerment books that promise guidance on mindfulness, inner peace, and personal transformation. Some emphasize meditation practices, while others discuss connecting with higher consciousness or finding purpose in life. I’m curious about your experiences have you read any books that truly impacted your spiritual journey? Which ones would you suggest for someone committed to personal and spiritual development?
