Meaning of Words
Parama-aṇu-parama-mahatva-antaḥ — (from the) smallest atom to the largest object. Parama added to aṇu, atom has the adjectival role of creating the superlative form of the noun ‘atom’, hence it is translated as smallest atom. Similarly parama added to mahatva means the largest object, and anta means limit, or end. This compound is translated – from the smallest atom to the biggest object. (This refers to the yogin’s ability to focus on the smallest to the largest gross or subtle object in meditation).

vaśīkāraḥ — mastery
