[Er.sandeep jain]

The objects that the senses (of touch, taste, smell, sight, and hearing) know are physical matter. Moreover, the senses are unable to apprehend these objects simultaneously.

Explanatory Note: 
The five senses of touch (sparśana), taste (rasana), smell (ghrāna), sight (caksu), and hearing (śrotra, karna) comprehend their respective sense-objects one by one; these cannot comprehend the sense-objects collectively. The reason is that the knowledge (jñāna) that arises on the destruction-cum-subsidence (ksayopaśama) of the knowledge-obscuring (jñānāvaranīya) karmas operates sequentially. The crow has two eyes with a single eyeball that moves extremely fast to the operational eye; to the onlooker it appears that it has two eyes with independent eyeballs. The crow cannot see with two eyes at the same time. The same is the state of the knowledge (jñāna) that arises on the destruction-cum-subsidence (ksayopaśama) of the knowledge-obscuring (jñānāvaranīya) karmas. It cannot know through all the five senses simultaneously. At any particular time, it operates through a single sense; all five senses cannot operate simultaneously. Knowledge through the senses, therefore, is indirect, dependent, and worthy of rejection.
