Shree Krishna is the biggest rasik. He is called Rasik Shiromani. Moreover, He is considered rasik in two ways- He grants ras to the devotees and He experiences the ras from His devotees. But why does God need ras from us? The reason is, the ras that He gets from Himself is called Swaroopanand and the ras which He grants devotees is called Swaroop-shaktya-anand, which is more sweeter.
