"One who is thus transcendentally situated at once realizes the Supreme Brahman and is fully joyful. He never laments nor desires to have anything; he is equally disposed to every living entity. In that state he attains pure devotional service unto Me." (Bg. 18.54)

To attain the platform of pure devotional service, one has to become spiritually pure and attain the brahma-bhuta platform, which is beyond material anxiety and material discrimination. When one approaches pure devotional service after realizing Brahman, one becomes attracted by pure devotional service. At such a time, by rendering devotional service, one gets a spiritual body with purified senses.
