"Rare Genius...ambidexterity-mirror writing, less than 1%population in world is capable of doing this!! #MyBrotherTheBest #JusticeForSushantSinghRajput #GlobalPrayersForSSR," Shweta captioned the clip.
However, the video shot from a top angle does not show Sushant's face.
The late actor's fans were in awe.
"He was so talented. Wish he could come back," a user commented.
"Need more people like him. Such a rare ability. Genius for sure," another one wrote.
Sushant was found dead in his Bandra flat on June 14. The Central Bureau of Investigation (CBI) is probing the death.
