Why did Radha become the Queen of Goloka?

[Shri Hrushikesh asked: Why did Radha become the Queen of Goloka? What was the main reason for Radha for being chosen as the Queen of Goloka over other 12 Gopikas who also reached Goloka?]

Swami replied: Radha is the incarnation of God Shiva and all other twelve Gopikas were only souls who were successful. Krishna is the incarnation of God Vishnu, and Radha is the incarnation of God Shiva. God Vishnu and God Shiva are one and the same (Śivaśca Nārāyaṇaḥ – Veda). If Krishna is the king, Radha must be the queen because both the posts are equal, and both Radha and Krishna are also one and the same God.
