There are several serious philosophical errors in just a couple of phrases. Saying that "the form of the soul is the source of all happiness" is wrong. The source is Krishna (sarva-kāraṇa-kāraṇam); the soul is receptáculo, not origin. Attributing this to jīva places it in the position of God. Emphasizing "eternal happiness" as the goal deviates the bhakti. The goal is prema and sevā, not enjoy yourself. The Gosvāmīs asked for service, not happiness. The speaker presents an egocentric spirituality that displaces Krishna from the center. Gauḍī Vaiṣṇavism is radically Krishna-centric: we exist for His pleasure, not He for our. This is refined karma, not śuddha-bhakti.
