Nithyananda, who sustained a fracture in the right forearm after he fell off his horse during a routine horse-riding exercise, was admitted to the Manipal Hospital on June 14, a release said.
The accident occurred when devotees who had gathered at the ashram for a meditation programme began cheering when they saw Nithyananda ride past on his horse. Hearing the noise, the animal panicked and bucked, resulting in the fall.
Starting on Friday, June 17, Nithyananda will resume his daily engagements, the release said.
Nithyananda landed in controversy in March last year after a local TV channel aired a purported video footage showing him in a compromising position with an actress.
He was arrested in Solan district in Himachal Pradesh in April and granted conditional bail in June.
Tamil Nadu police had registered cases including rape against Nithyananda before they transferred them to their counterparts in Karnataka which handed over the probe to CID.
