The last phase of knowledge is the Absolute Truth. You have to go up to that. So that Absolute Truth, if you go on speculating, panthās tu koṭi-śata-vatsara-sampragamyo (BS 5.34), that will not be possible. Śata-vatsara-sampragamyo, by hundreds and hundreds of years, if you go on with speed . . . What is that speed? Panthās tu koṭi-śata-vatsara-sampragamyo vāyor athāpi. Aeroplane, airplane, vāyor athāpi. And what is the speed? Vāyor athāpi. Panthās tu koṭi-śata-vatsara sampragamyo vāyor athāpi. Manaso vayu: by the speed of air and mind. Mind is very speedy. You are sitting here, you can immediately remember ten thousand miles away, it is so speedy. So even by the mind's speed you cannot, by going over the space, koṭi-śata-vatsara, many millions of years still it remains unknown. So this is not the way to understand the Absolute Truth, but if we accept the Vedic process, avaroha panthā, when the knowledge comes from the Absolute Truth, then it is possible.
So we Kṛṣṇa conscious, I mean to say, devotees, we try to understand the Absolute Truth by the grace of the Absolute Truth. The Absolute Truth is Kṛṣṇa. Kṛṣṇa says, mattaḥ parataraṁ nānyat kiñcid asti dhanañjaya (BG 7.7): "I am the Supreme." Vedaiś ca sarvair aham eva vedyam (BG 15.15). In this way, if we try to understand Kṛṣṇa as He is speaking, as they are stated in the śāstra, as it is accepted by the ācāryas, then we can have some trace of the Absolute Truth. Just like Kṛṣṇa says,
- athavā bahunaitena
- kiṁ jñātena tavārjuna
- viṣṭabhyāham idaṁ kṛtsnam
- ekāṁśena sthito jagat
- (BG 10.42)
The expansion of the Absolute Truth, how it is working, so Kṛṣṇa summarized before Arjuna that this material world, material world . . . Ekāṁśena sthito jagat, this material world. What is that material world? This material world, we see only one universe to our vision. Similarly, there are millions of universes. Yasya prabhā prabhavato jadad-aṇḍa koṭi (BS 5.40). Jagad-aṇḍa means one universe, and in each universe, koṭiṣu aśeṣa. Yasya prabhā prabhavato jagad-aṇḍa-koṭi-koṭisv aśeṣu vibhūti-bhinnam (BS 5.40). There are millions of planets, and each planet is different from here. That is God's creation.
