In the thirteen verse of his Cidvilāsastava (‘Hymn to the Play of Consciousness’), Amṛtānanda teaches about the deeper aspects of kāmakalā as follows:
काम ऊर्ध्वगतबिन्दुराननं भानुरेष तदधोगतौ स्तनौ ।
चित्रभानुशशिनावुभौ कला योनिरत्र सपरार्धकुण्डली ॥ १४ ॥
kāma ūrdhvagatabindur ānanaṃ bhānur eṣa tad adhogatau stanau |
citrabhānuśaśināv ubhau kalā yonir atra saparārdhakuṇḍalī || 14 ||
“Desire (kāma), [which in the kāmakalā diagram] is the upper bindu that is the face [of the Goddess], is the sun. The active [dividing] power (kalā) is the two breasts below that [upper bindu] which correspond to both fire and the moon. Here the yoni is the lower half of kuṇḍalinī [in the form of the phoneme HA].” (translation by Ben Williams)
