antarhitaś ca sthira-jańgameṣu
brahmātma-bhāvena samanvayena
vyāptyāvyavacchedam asańgam ātmano
munir nabhastvaḿ vitatasya bhāvayet
antarhitah -- present within; ca -- also; sthira -- all nonmoving living bodies; jangameshu -- and all moving forms of life; brahma-atma-bhavena -- by realization that he himself is pure spirit; samanvayena -- as a result of the different contacts (with different bodies); vyaptya -- because of being all-pervading; avyavacchedam -- the feature of being undivided; asangam -- being unattached; atmanah -- possessed by the Supersoul; munih -- a sage; nabhastvam -- the similarity with the sky; vitatasya -- of the expansive; bhavayet -- should meditate upon.
Although air exists within the sky, the sky, or space, is different from air. Even in the absence of air, space or sky is present. All material objects are situated within space, or within the vast material sky, but the sky remains undivided and, although accommodating all objects, never actually mixes with anything. In the same way one can understand the situation of both the individual soul and the Supersoul. The individual soul is all-pervading, because there are innumerable jivatmas, which enter within all things; yet, as confirmed in Vedic literature, each individual atma remains infinitesimal. The Svetasvatara Upanishad (5.9) states,
balagra-sata-bhagasya
satadha kalpitasya ca
bhago jivah sa vijneyah
sa canantyaya kalpate
"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." The same is stated in Srimad-Bhagavatam:
kesagra-sata-bhagasya
satamsah sadrisatmakah
jivah sukshma-svarupo 'yam
sankhyatito hi cit-kanah
[Cc. Madya 19.140]
"There are innumerable particles of spiritual atoms, which are measured as one ten-thousandth of the upper portion of the hair."
The Supreme Personality of Godhead, however. is all-pervading because He Himself is personally present everywhere. The Lord is known as advaita, or indivisible. Thus the same unique Personality of Godhead exists everywhere, just like the sky, and yet is not attached to anything, although everything is resting within Him. The Lord Himself has confirmed this analysis of His all-pervasiveness in Bhagavad-gita (9.6):
yathakasa-sthito nityam
vayuh sarvatra-go mahan
tatha sarvani bhutani
mat-sthanity upadharaya
"As the almighty wind, blowing everywhere, always rests in ethereal space, know that in the same manner all beings rest in Me."
Therefore, although both the jiva soul and the Supersoul are said to be all-pervading, it should be remembered that there are innumerable individual jiva souls, whereas there is only one Supreme Personality of Godhead. The Lord is always supreme, and one who is actually a thoughtful sage never doubts the supreme position of the Lord.
