Are our senses actually defective or do we just have to be alert while taking in sense information?

Question from Deepak Tripathi Prabhu are our senses actually defective? isn’t it that actually we just have to make sure that we don’t get carried away by the information that the senses bring to us and that we remain alert and aware then the senses being God’s creation will not be defective answer the word defective can be used in various senses and here it is used in a particular technical sense to refer to the fact that the senses are having the four defects these four defects are the Brahma Pramad, Vipralipsa and Karnapada so Karnapada is the limitations of the senses that as we know science has told us that we can see only a small visible spectrum in the giant spread of the electromagnetic spectrum so each of our senses has thresholds, we can hear only certain frequencies so that is imperfect senses and after imperfect senses then there is the tendency to be put in illusion that means if after drinking hot water we drink a cold drink, it appears colder than what it would be if we had before that drunk something even colder so that is the tendency to be illusioned tendency to commit mistakes is that means just because of our negligence or carelessness or something like that we mistake one thing to be another and tendency to cheat is to cover up the limitations of our knowledge we try to find out we try to make up make up explanations of what things may be like, so these are the four defects and these four defects are present intrinsically irrespective of how alert we are to protect the information that is coming into our senses no matter how alert I am I will still have the limitation of the visible spectrum and I will not be able to say a dog, hear a dog’s whistle now there is also the mention in the question about we having astral senses yes the Bhagavatam third canto mentions that in addition to our gross senses there are senses at three levels we have our gross senses which are at the sensory level then there are the subtle senses which are at the level of subtle body and then there are the spiritual senses which are the senses of the soul proper with which the soul performs pastimes with Krishna in the spiritual world so senses exist at all three levels and right now it is only our gross senses are active but in some exceptional situations like near death experiences when the soul when the soul and the body are separated out then the person can see directly with the subtle senses even when the gross senses like the gross eyes say are closed and the body is unconscious so there are even cases of people who are blind throughout their life being able to see during their near death experiences so this indicates that there are definitely subtle senses so the access to subtle senses however is normally not available to us and because of that we cannot say for sure that what we are perceiving if some people have some paranormal experiences that those experiences are actually the accurate perceptions coming from our subtle senses they may well be the hallucinations that we may be having they may just be the fantasies of a mind gone restless so by certain mystic powers by certain sadhana by certain yogic sadhanas one may be able to gain access to these subtle senses also but even then if one has access that does not make one omniscient like God so the basic point of talking about the four defects which are talked about say for example by Jeeva Goswami in his Sat Dharmas by Chaitra Charita which are generally known in the Vedic tradition the basic reason for talking about these four defects is to indicate that how we cannot have omniscience and we cannot be God and therefore if we want to have proper understanding of our position and our role in the world in the universe then we have to consult a superior intelligence that is the intelligence of God coming through scripture and the scriptures are like a manual which guide us to act properly in this world so the important point in talking about the four defects is that they are meant to serve a particular purpose that is to give us information for interacting in the world and they do give that information but beyond that they have limitations and those limitations are there because we are not God and the limitation of the senses remind us that we are not omniscient and the presence of subtle senses doesn’t detract from the fact that still even if somebody has access to the astral senses still that person never becomes omnipotent omniscient, that person always maybe have more knowledge and more perception than other common people but still the person is never as knowledgeable as completely knowledgeable as God is so because the senses limit the knowledge.
