In fourth brahmana, the Upanishad presents a dialogue between a husband and wife, as Yajnavalkya and Maitreyi, on nature of love and spirituality, whether and how is Atman related to deep connection and bonds between human beings. Yajnavalkya states that one doesn't connect with and love forms, nor does one connect or love mind, rather one connects with the Self, the Soul of one's own and one's beloved. All love is for the sake of one's Self, and the Oneness one realizes in the Self of the beloved. He then asserts that this knowledge of the Soul, the Self, the Brahman is what makes one immortal, the connection immortal. All longing is the longing for the Soul, because Soul is the true, the immortal, the real and the infinite bliss.
