When one is situated in his spiritual body, which is beyond this gross and subtle material body, he is fit to serve Radha and Krsna. That body is called siddha-deha. The living entity attains a particular type of gross body in accordance with his past activities and mental condition. In this life the mental condition changes in different ways, and the same living entity gets another body in the next life according to his desires. The mind, intelligence and false ego are always engaged in an attempt to dominate material nature. According to that subtle astral body, one attains a gross body to enjoy the objects of one's desires. According to the activities of the present body, one prepares another subtle body. And according to the subtle body, one attains another gross body. This is the process of material existence. However, when one is spiritually situated and does not desire a gross or subtle body, he attains his original spiritual body. As confirmed by the Bhagavad-gita (4.9): tyaktva deham punar janma naiti mam eti so 'rjuna.

One is elevated to the spiritual world by the spiritual body and is situated either in Goloka Vrndavana or in another Vaikuntha planet. In the spiritual body there are no longer material desires, and one is fully satisfied by rendering service to the Supreme Personality of Godhead, Radha and Krsna. This is the platform of bhakti (hrsikena hrsikesa-sevanam bhaktir ucyate). When the spiritual body, mind and senses are completely purified, one can render service to the Supreme Personality of Godhead and His consort. In Vaikuntha the consort is Laksmi, and in Goloka Vrndavana the consort is Srimati Radharani. In the spiritual body, free from material contamination, one can serve Radha-Krsna and Laksmi-Narayana. When one is thus spiritually situated, he no longer thinks of his own personal sense gratification. This spiritual body is called siddha-deha, the body by which one can render transcendental service unto Radha and Krsna. The process is that of engaging the transcendental senses in loving devotional service. This verse specifically mentions, sakhi-bhave paya radha-krsnera carana: only transcendentally elevated persons in the mood of the gopis can engage in the service of the lotus feet of Radha and Krsna.
