By Swami Harshananda
Manas literally means ‘that by which one thinks’.
It is an aspect of the antahkaraṇa or internal organ which is responsible for saṅkalpa or general thinking. It includes willing and vikalpa or doubting. It is the combination of the sattva-aspect of all the five tanmātras or primordial elements.
