How did God get entertainment due to the mad love of Radha, who is also an incarnation of the same God?

[Ms. Laxmi Thrylokya asked: Padanamaskaram Swami, You taught us that Unimaginable God created this creation because He was bored of continuous bliss (Ānandā) being alone. Creation being a second entity would give blissful entertainment (Rasa) to Him. Creation being different from creator generates duality. This duality i.e., God and non-God (creation) is the reason for entertainment. God gets maximum pleasure when a soul (non-God) loves God overcoming all the worldly bonds. Now, let us consider the example of Radhā-Krishna and Gopikas. Lord Krishna was so pleased with the mad love of Radhā that He created a new loka called Goloka above His head and made Her the queen of Goloka. But, Rādhā is incarnation of Lord Shiva who is none other than Lord Krishna. Both have unimaginable God merged with them. Both are one. This fact is standing against the principle of duality. How did God get entertainment here? Kindly enlighten us. -At Your Divine Lotus Feet, Laxmi Thrylokya]

Swami Replied: There are two types of dualities in this topic:- 1. Duality between God and non-God soul created for the entertainment of God because, God is bored with bliss in monistic state (without second item). 2. Duality between Krishna and Raadhaa, which is superficial only and not internal duality because Krishna as God Vishnu and Raadhaa as God Shiva are one and the same. The first duality is the overall general duality between God and creation. The second duality is a tiny part of the general overall first duality. The second duality is not contradicting the first duality. I will explain this with an example: N.T. Rama Rao wanted to get an entertainment by seeing a new film created by him for his entertainment, in which he himself acted as Krishna and Duryodhana. Now, the film is shot and N.T. Rama Rao is watching that film and getting entertainment. N.T. Rama Rao and the film come under the first duality (God entertaining with non-God soul). The second duality is between Duryodhana and Krishna in the film seen by N.T. Rama Rao. Is this situation possible or not possible? It is possible because N.T. Rama Rao is seeing the above said film and is getting entertained. If this is possible, why not the case of God entertained by the creation is simultaneously continuing while God acted in two roles simultaneously in the cinema that is entertaining God? What is the contradiction here?
