(Sūrya): The Sun. The expression of masculine, dynamic energy. In the human body, pingala nadi (the solar energy channel) governs the burning processes, while ida nadi (the lunar energy channel) is cooling and calm. Governing daytime, activity, and the spending of energy, surya is connected to time and death. It is the principle of truth and reward, also called Dharma Raja (The Master of Justice), both in its aspects of noble stringency and the power of terrible decisions.
