基師云：若懃精進妙智令堅，放逸懈怠妙智乃退。沈，謂惛沈。量謂度測掉舉也。助伴者，同時心所也。

Master Ji says: If one exerts energetic effort, subtle wisdom is made firm; through negligence and indolence, subtle wisdom falls away. "Sinking" refers to torpor. "Agitation" refers to measuring, calculating, and restlessness. "Companions" refers to simultaneous mental factors.
