According to Ramanuja's teachings, the jivatma after attaining moksha performs divine service to God which is known as kainkarya. It is further stated that this kainkarya comes out of the nature or swarupa of jivatma and hence is a source of joy for the jivatma.
However, from a logical point of view, if one were required to perform service in the state of moksha, then it reduces the appeal of moksha as a desirable place to attain because we are involved in service similar to what we are doing in this mundane human life.
Even though we face sufferings in life, we are still involved in doing things which give pleasure to us such as hobbies, playing sports, etc. Will we be denied such things in the state of moksha, since we are only expected to perform divine service?
Finally, what is the scriptural support for the concept of kainkarya or divine service?
To sum it all, how can we be convinced that moksha involving kainkarya or divine service is a desirable thing and is not something mundane or boring?
