‘Sense’ is the distinguishing sign between the conscious and unconscious, living and non-living.
Any living being experiences different situations through its capacity of sense which is defined as a feeling or a faculty by which a body perceives any stimulus, externally or internally. The word sensory has evolved from the word sense.
The human experience of life is fundamentally shaped by senses. This process happens through a system which involves the mind which analyses the impulses or messages that are understood by the sensory objects like the eyes, ears, nose, tongue, skin. Through sight, sound, touch, taste and smell we constantly interact with the world around us, receiving impressions that influence our thoughts, emotions and behaviour. These senses are not merely biological instruments, they are gateways through which we perceive reality, form meanings and experience pleasure or pain. The objects of our senses have a profound effect on our inner state, either nurturing happiness or contributing to stress and mental agitation. Understanding the effects between the senses, their objects and their effect on mind is therefore essential for achieving balance, well being and contentment in life.
