Is the occupational duty of Kali-yuga devotional service?

What to speak of Kali-yuga, devotional service is the occupational duty of all yugas, for all times, and for all people. Activities like karma, jyana, and yoga are only temporary duties. They are not the spontaneous duties of living entities. Only devotional service is the eternal occupational duty of liberated souls. The occupational duties of conditioned souls afflicted by anarthas are called karma, jyana, yoga, tapa and vrata.
