Got a few minutes? Download this book, "The Wisdom of Serenity" to enjoy during moments of downtime.
The author, Christopher Foster, writes The Happy Seeker, a blog about spirituality and its effect on the soul.
The book is just 35 pages including the cover and bio, but offers short little truths about life, such as "Your body has limitations" but "there is another part of you that is forever free."
It's a free, downloadable book, so the only cost is time.
