A former employee of Carlos Santana is suing the guitarist and his wife for $100,000 (£52,400), saying he was sacked for not being "closer to God".
Carlos Santana won a record nine Grammys in 1999
Bruce Kuhlman alleges he was fired because the Santana's spiritual advisor saw him as too old for enlightenment.
The lawsuit also says he was cut from a $250,000 (£131,077) bonus from the licensing operation he ran.
A lawyer for Mr Santana had no comment on the lawsuit, which was filed in Los Angeles.
Mr Kuhlman, 59, said he was subjected to a "calibration" test by guru Dr Dan.
Slurring male employees
He alleges that Dr Dan said he was too old to be enlightened and "that the more enlightened a person was, the closer to God he was and the better employee he was".
He also accused Deborah Santana of constantly slurring male employees, hiring only females who had been "calibrated" by Dr Dan.
Mr Kuhlman started as personal assistant to Carlos Santana in 1988, eventually running his licensing division, River of Colors.
He says he was sacked after missing an appointment with Dr Dan.
Latin guitarist Mr Santana is one of the world's most respected musicians, winning 10 Grammys for his work, nine of which were awarded in 1999.
He and his wife also work with young people and Aids charities.
