"Holy Smokes: Loose Herbs & Hot Embers for Intense Group Smudges & Smoke Prayers" by Amy Moonlady Martin is for anyone wanting to purify or offer prayers using herbal smoke. This book is a must for shamans and ceremony leaders!

Burn special blends of loose herbs on hot barbeque charcoal to discover a new method for smudges and ceremonies rooted in the ancient Mesoamerican tradition of immersion smudging.
 
Go far beyond the usual smudge sticks. Utilize woods, resins, leaves, and even seeds and flowers for smudges that create billows of aromatic smoke to purify several people at once. Make lunar, solar, masculine, feminine smudges and more.
