WHAT KRISHNA IS DOING IN GOLOKA?

Actually, we should always remain blissful. Why?

Because we are the parts and parcels of Krishna.

Krishna is always blissfully performing lilas in His kingdom.

So, we too should be blissful.

But, we make our lives complicated more and more by attaching with the materials.

Ok, what Krishna is doing in Goloka? What we should do?

SRILA PRABHUPADA SAYS:

“The Isopanisad states, "Although fixed in His abode, the Personality of  Godhead is swifter than the mind and can overcome all others running. 

The powerful demigods cannot approach Him. Although in one place, He controls those who supply the air and rain. He surpasses all in excellence."

The Brahma-samhita says something similar:  “Goloka eva nivasaty akhilatma-bhutah”. Although Krsna is always in Goloka Vrndavana, He is simultaneously in the hearts of all living beings. 

Krsna has no duties to perform in Goloka. He is simply enjoying in the company of His associates--the gopis, the cowherd boys, His mother and father,  His cows and calves, etc.  

When Krsna enacted His pastimes five thousand years ago in Vrndavana, India, He would go every day with His cowherd boyfriends and their calves and cows to play in the forest on the bank of the Yamuna River. And often Kamsa would send some demon to try to kill Krsna and His friends. Yet the cowherd boys would continue enjoying their pastimes without anxiety because they were so confident of Krsna's protection. That is spiritual life, which begins with surrendering to Krsna.

Krishna  is completely free. And His associates are even freer than He is,  because when they seem to be in danger, Krsna feels some anxiety about how to save them.  But His associates feel no anxiety.  They simply think, "Oh, Krsna is here. He will protect us."
