antarhitaś ca sthira-jaṅgameṣu
brahmātma-bhāvena samanvayena
vyāptyāvyavacchedam asaṅgam ātmano
munir nabhastvaṁ vitatasya bhāvayet
antarhitaḥ - present within; ca - also; sthira - all nonmoving living bodies; jaṅgameṣu - and all moving forms of life; brahma-ātma-bhāvena - by realization that he himself is pure spirit; samanvayena - as a result of the different contacts (with different bodies); vyāptyā - because of being all-pervading; avyavacchedam - the feature of being undivided; asaṅgam - being unattached; ātmanaḥ - possessed by the Supersoul; muniḥ - a sage; nabhastvam - the similarity with the sky; vitatasya - of the expansive; bhāvayet - 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 jīvātmās, which enter within all things; yet, as confirmed in Vedic literature, each individual ātmā remains infinitesimal. The Śvetāśvatara Upaniṣad (5.9) states:
bālāgra-śata-bhāgasya
śatadhā kalpitasya ca
bhāgo jīvaḥ sa vijñeyaḥ
sa cānantyāya 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 Śrīmad-Bhāgavatam:
keśāgra-śata-bhāgasya
śatāṁśaḥ sādṛśātmakaḥ
jīvaḥ sūkṣma-svarūpo ’yaṁ
saṅkhyātīto hi cit-kaṇaḥ
“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-gītā (9.6):
yathākāśa-sthito nityaṁ
vāyuḥ sarvatra-go mahān
tathā sarvāṇi bhūtāni
mat-sthānīty upadhāraya
“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 jīva soul and the Supersoul are said to be all-pervading, it should be remembered that there are innumerable individual jīva 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.
