Any person who is always joyful and untouched by any distress is called happy.
As far as Krsna's enjoyment is concerned, it is stated that the ornaments which decorated the bodies of Krsna and His queens were beyond the dreams of Kubera, the treasurer of the heavenly kingdom. The constant dancing before the doors of Krsna's palaces was not to be imagined even by the demigods in the heavenly kingdom. In the heavenly kingdom, Indra always sees the dancing of the society girls. But even Indra could not imagine how beautiful were the dances being performed at the gates of Krsna's palaces. Gauri means white woman, and Lord Siva's wife is called Gauri. The beautiful women residing within the palaces of Krsna were so much whiter than Gauri that they were compared to the moonshine, and they were constantly visible to Krsna. Therefore, no one can be enjoying more than Krsna. The conception of enjoyment is beautiful women, ornaments and riches. And all of these things were fabulously present in the palaces of Krsna, defeating even the imagination of Kubera, Lord Indra or Lord Siva.
Not even a slight distress can touch Krsna. Once some of the gopis went to the place where the brahmanas were performing sacrifices and said, "Dear wives of the brahmanas, you must know that not even a slight smell of distress can touch Krsna. He knows no loss, He knows no defamation, He has no fear, He has no anxiety, and He does not know calamity. He is simply encircled by the dancers of Braja and is enjoying their company in the rasa dance."
