俱舍論疏 4.50

4.50

[The root text of the] Treatise states: "Attention (manaskāra) means that which is able to alert the mind." The Nyāyānusāra states: "That which directs the mind and mental factors, causing them to be alerted toward an intentional object, is called attention. In worldly convention, this is called 'keeping in mind.'" The Commentary explains: When the minds and mental factors are submerged and not active, they are alerted and aroused by the power of attention, which urges them to act and enables them to adhere to their intentional object; this is what is called in worldly convention 'keeping one's mind on this.'
