The cit-kana or the atomic sentience spiritual soul, which is identified as a spiritual spark is the energetic identity of the Brahmin. It is present everywhere in the universe or the universe is made of it. It is the smallest part of the supreme consciousness which navigate the creation. This cit kana is the consciousness of the Satcitānanda. You all are aware about the God particle or boson particle, it is nothing but the cit-kana, mentioned 1000s years back in Vedic scriptures.
balagra-sata-bhagasya ,satadha kalpitasya ca
bhago jivah vijneyah, sa canantyaya kalpate
~ Svetasvatara Upanisad: 5.9
“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.”
✒ Similarly the same version is stated again on Chaitanya Charanamrita:
jivah sukshma-svarupo ‘yam sankhyatito hi cit-kanah
~Cc. Madya 19.140
“If we divide the tip of a hair into a hundred parts and then take one of these parts and divide it again into a hundred parts, that very fine division is the size of but one of the numberless living entities. They are all cit-kana, particles of spirit, not matter.”
✒ The dimension of the living entity is given as one ten-thousandth of the tip of a hair. The human hair is about 100 microns in diameter, and the tip of an uncut hair tapers to about 10 microns, or 10 millionths of a meter. Therefore according to the Vedic scriptures, the size of the particle of the jiva or spirit soul is about .0001 microns, or .1 nanometers.
✒ Again “Cit-kana” no other than Boson particle/God Particle through which has Knowledge Value (KV) = 10-38 (Planck Number). Considering that consciousness is the attribute of Knowledge, therefore Boson should containing consciousness element factor (CEF). If we look at KV over 9.0 or beyond human maximum possible KV, simply we could mentioned it is the domain of spiritual or divine Universe. (Note: the Boson particle was named bason after Saytendranath Bose a famous Bengali scientist worked with Albert Einstein). Now scientists think that the universe is made up of micro consciousness particles which they called God particles. With thousands of years of vedic tradition this cit-kana is very well known phenomena, the sages see this feel this and play with this without modern instrument, they simply use the greatest instrument of all the human body. Our scriptures mentioned it again and again that the supreme consciousness can be found in everything that’s why Hindus see God in everything.
yad eveha tad amutra
yad amutra tad anv-iha ~Katha Upanisad 4.10
Whatever is down here, the same is over there, and what is over there is replicated over here.
yasmin sarvani bhutany
tatra ko mohah kah soka
ekatvam anupasyatah~ Isa Upanisad 7
One who always sees all living entities as spiritual sparks, in quality one with the Lord, becomes a true knower of things. What, then, can be illusion or anxiety for him?
This is the result of misidentifying with the material world. When we theoretically understand that we, as a unit of consciousness (cit-kana), are different from matter,
✒ In the Mundaka Upanishad (3.1.9) the measurement of the atomic spirit soul is further explained:
eso ’nur atma cetasa veditavyo
yasmin pranah pancadha samvivesa
pranais cittam sarvam otam prajanam
yasmin visuddhe vibhavaty esa atma
“The soul is atomic in size and can be perceived by perfect intelligence. This atomic soul is floating in the five kinds of air (prana, apana, vyana, samana and udana), is situated within the heart, and spreads its influence all over the body of the embodied living entities. When the soul is purified from the contamination of the five kinds of material air, its spiritual influence is exhibited.”
✒ Even today modern science is trying hard to prove the existence of the God particle where a realized sage can see this with the spiritual eyes.
anor aniyan mahato mahiyan
atmasya jantor nihito guhayam
tam akratuh pasyati vita-soko
dhatuh prasadan mahimanam atmanah ~ Katha Upanisad 1.2.20
“Both the Supersoul [Paramatma] and the atomic soul [jivatma] are situated on the same tree of the body within the heart of the living being. Only one who has become free from all material desire and lamentation can understand the glories of the soul by the grace of the Supreme.”
