There are a ton of ways to promote a spiritual book like yours.
The best way is to find about ten top people who are writing about sex, drugs, or enlightenment (or all three). Invite them to
interview you. I bet you do a great podcast interview.
There are also a lot of Internet radio shows at BlogTalkRadio.com and elsewhere that cover at least one of those three topics: sex, drugs, and rock’n’roll (or enlightenment). They should all be eager to interview you as well.
