This body is given by the father and mother at a certain date. Then it stays, say for some times. It grows. Then it gives some by-products, from this body, there will be so many children. Or from the trees, there will be so many fruits and seeds. Then dwindling, then becomes older, and vanish. This is the nature.
So here we are getting information that acchedyo 'yam adāhyo 'yam akledyo 'śoṣya eva ca, nityaḥ sarva-gataḥ. This is another qualification of the living entities: sarva-gataḥ, "everywhere." The rascal scientist says there is no living entity in the moon planet or sun planet. This is rascaldom. There is. Otherwise, how Kṛṣṇa says sarva-gataḥ? Any, everywhere there is living entities. This is a false theory.
We can see practically. We see there are living entities in the water. There are living entities in the air. There is living entity within the earth. There is living entities in so many ways. Why not in other planets? Where is the difference between this planet and that planet? This is also made of five elements—that is also meant of, made of five elements. Here, the earthly element is very prominent, and the sun globe, the fire element is very prominent.
So this material world is made of these five elements. Bhūmir āpo 'nalo vāyuḥ khaṁ mano buddhir eva ca (BG 7.4). So Kṛṣṇa says sarva-gataḥ. The living entities are everywhere. Kṛṣṇa is also within everywhere.
Aṇḍāntara-stha-paramāṇu-cayāntara-stham (Bs. 5.35). Kṛṣṇa is within this universe. Kṛṣṇa is within your heart. Not only your heart, but in everyone's heart. Īśvaraḥ sarva-bhūtānāṁ hṛd-deśe arjuna tiṣṭhati (BG 18.61). Now, if you are a great scientist, take one insect . . . there are so many insects, we have seen, especially in the book, less than the full stop. Now, if you are a great scientist, find out where is the heart of this insect, and where is Kṛṣṇa.
But Kṛṣṇa says, sarva-gataḥ: everywhere there is Kṛṣṇa. Unless there is Kṛṣṇa, there is living entity, how that small, full-stop–like insect is moving? There is everything. The physiological condition is there. There is heart also. You cannot make that. You have imitated a big bird, aeroplane, flying, but just imitate the small insect which is also flying.
So there are so many questions that if we actually, philosophically study, then we can see vāsudevaḥ sarvam iti sa mahātmā sudurlabhaḥ (BG 7.19), how Vāsudeva, Kṛṣṇa, is acting. Aṇḍāntara-stha-paramāṇu-cayāntara-stham (Bs. 5.35). So here the living entity is described as sanātana.
And the process by which we can understand our sanātana nature, that is called sanātana-dharma. Not that having a big tilaka and considering this rascal lump of matter as "I am brāhmin. This body is brāhmin, and sanātana-dharma." This is all nonsense.
