14_Bhagavad Gita: Chapter 2, Verse 17 to 20

<p> This verse more clearly explains the real nature of the soul, which is spread all over the body. Anyone can understand what is spread all over the body: it is consciousness. Everyone is conscious of the pains and pleasures of the body in part or as a whole. This spreading of consciousness is limited within one's own body. The pains and pleasures of one body are unknown to another. Therefore, each and every body is the embodiment of an individual soul, and the symptom of the soul's presence is perceived as individual consciousness. This soul is described as one ten-thousandth part of the upper portion of the hair point in size. The&nbsp;<em>Svetasvatara Upanisad&nbsp;</em>confirms this:</p><p><em>balagra-sata-bhagasya satadha kalpitasya ca</em></p><p><em>bhago jivah sa vijneyah sa canantyaya kalpate.</em></p><p>"When the upper point of a hair is divided into one hundred parts and again each of such parts is further divided into one hundred parts, each such part is the measurement of the dimension of the spirit soul."&nbsp;<em>(Svet.&nbsp;</em>5.9) Similarly, in the&nbsp;<em>Bhagavatam&nbsp;</em>the same version is stated:</p><p><em>kesagra-sata-bhagasya satamsah sadrsatmakah</em></p><p><em>jivah suksma-svarupo 'yam sankhyatito hi cit-kanah</em></p><p>"There are innumerable particles of spiritual atoms, which are measured as one ten-thousandth of the upper portion of the hair."</p><p> Therefore, the individual particle of spirit soul is a spiritual atom smaller than the material atoms, and such atoms are innumerable. This very small spiritual spark is the basic principle of the material body, and the influence of such a spiritual spark is spread all over the body as the influence of the active principle of some medicine spreads throughout the body. This current of the spirit soul is felt all over the body as consciousness, and that is the proof of the presence of the soul. Any layman can understand that the material body minus consciousness is a dead body, and this consciousness cannot be revived in the body
