“The moon,
whose rays are auspicious for the gathering of medicinal herbs,
is the god of herbs,
whilst the light of the sun gets to the bottom of all impurities.
This is why we recite Mantra to these two stars,
during the preparation of Āyurveda remedies.”
– T Krishnamacharya

“The terms Ha and Ṭha also represent
two extreme sides of a wavering mind.
Ha often is meant to represent the sun, Ṭha the moon.
Suṣumṇā in the middle Nāḍī.
Prāṇa in the Ha and Ṭha represents
a confused and wavering mind.
Prāṇa in the  Suṣumṇā represents a clear, steady mind.
Hence, Jñāni is one whose Prāṇa is in Suṣumṇā
and Ajñāni is one whose Prāṇa is still
in the opposite two Nāḍī, Ha and Ṭha.”
– TKV Desikachar Religiousness in Yoga

Chapter Seventeen Page 246-247

“Within the energetic processes in Haṭha Yoga
the concept of Candra is that which can direct
Prāṇa and Apāna in order to influence the activities of Sūrya.”
