The 85-year-old, who plays Ken Barlow in the ITV soap, is apparently a member of the Pure Love spiritual movement which believes in reincarnation and angels.
His new guide, which is said to be released next May, aims to help those he believes could benefit from his advice.
A source said told the Sun: “This is not just another soap autobiography.
“Bill wants to share with fans his tips for living a balanced, happy life.
“He is genuinely hoping that by sharing his thoughts, he can help others.
The ITV actor and soap regular reportedly became a healer for the Cheshire-based Pure Love group in 2013.
