Asaram, 72, who was arrested from his ashram in Indore in Madhya Pradesh last week, sought bail claiming that police erred in booking him under rape charge, which is non-bailable.
He claimed if the minor girl's complaint was found to be true, it would at best amount to a rape attempt.
Manan told the court that the spiritual guru should be granted bail as even the alleged rape attempt was a bailable offence.
Asaram was on Monday sent to 14 days' judicial custody by a Jodhpur district court after questioning at a guest house of the Rajasthan Armed Constabulary.
The 16-year-old girl alleged that the sexual assault took place on Aug 15 at Asaram's ashram outside Jodhpur city. The spiritual guru has denied the charge. Police, however, claimed they had a water-tight case against him.
