Goloka Dham is spiritual or Nitya Vrindavana, where Sri Radha Krishna resides with all the gopis and gopas. Each and every female in Goloka is the expansion of Maa Radharani's spiritual body and each and every male in Goloka is the expansion of Sri Krishna's spiritual body.
Rādhā Kṛṣṇa eternally resides in Goloka in their original form and in the Vaikuntha as Laksmī Nārāyana.
