In plain words
The full Avatāras bring Māyā under their control, go beyond Māyā, and live in divinity itself, in order to make their own divinity known to the world. As the moment requires, He acts as though bound by Māyā, and rules the world with a divinity that has no connection at all with Māyā. The Rāma Avatāra acted as though subject to Māyā, practised Dharma Himself, lived it, and gave it to the world for the welfare of the world. The Kṛṣṇa Avatāra is not like that. He kept Māyā under His own command and made Himself known purely as a Līlā Avatāra. That is why, many times over in the Bhāgavatam, Vyāsa declared, 'Līlāmānuṣa vigraha.' The whole Bhāgavatam has proclaimed Kṛṣṇa's qualities, taught the world His wondrous tattva of play, and given it delight. So in the Kṛṣṇa Avatāra He gave His tattva, His divinity, to the world not only in practice but in His teachings and proclamations too.
He is beyond the guṇas. But for the uplift of the world He acted as one who has guṇas, practised it Himself, and gave the world delight. 'Whatever He did, He did for the good of the world,' said 'Sañjaya uvāca'. Whatever He did and whatever He said was for the good of the world, not for Himself. For the world. Unable to recognise this supreme truth, the world has brought to God's qualities some kinds of blemish, along with their own. 'Yadbhāvaṃ tadbhavati': people take hold of divinity too in that same way, on the basis of man's own feelings.
Prema is made of nectar. It is the sweetest of the sweet. Those who drank this power of the flavour of Bhakti were the Gopīs. But those Gopīs did not desire any Mukti, any Jñāna or any Vairāgya. The Gopīs could not find in anything else the Ānanda that is in a divinity beyond Bhakti. Nārada gave this a new name, parama-bhakti. The devotees of that day, embodiments of this parama-bhakti, regarded the Paramātma as their intimate and their treasure, and experienced Him so. The Gopīs who drank this Prema for God were intoxicated, maddened, maddened with Prema, and wandered about like mad women. They left their houses and went into the forests. The moment they heard the music of Kṛṣṇa's flute they forgot themselves. They recognised that God is the embodiment of Śabda Brahman. They forgot all the things there are in the world.
