Actor Hrithik Roshan, who was earlier married to Sussanne Khan, believes that the only way to live on forever is to etch your name in other people's hearts.

The actor on Sunday posted a photograph of his son Hridaan, who is seen writing his name on sand with his hands.

`That won't last my son, the only way to live on forever is to etch your name in other people's hearts. #OnlyLoveLasts,` Hrithik captioned the image, which he shared on Twitter.

The "Bang Bang!" star also posted a photograph of him gearing up for zip-line.

`Can u spot us? Its a perfect day 4 fathers n sons 2 conquer sum fears n hv some fun! #HappyFathersDay #zipline,` he captioned the image.

On the movie front, Hrithik is currently busy shooting for his upcoming film `Mohenjo Daro`, directed by Ashutosh Gowariker.
