Kṛṣṇa comes to teach us. Kṛṣṇa is very, very anxious.
yadā yadā hi dharmasya
glānir bhavati bhārata
tadātmānaṁ sṛjāmy aham
(B.G.4:7)
Kṛṣṇa comes Himself, Kṛṣṇa leaves behind Him His word. Vapu and vāṇī. Vāṇī means the words. That is also Kṛṣṇa. That is also... Just like we do not see Kṛṣṇa now. We can see Kṛṣṇa if we actually advance. Here is Kṛṣṇa. But they will say, "Oh, this is an idol. This is an idol. This is not Kṛṣṇa." But Kṛṣṇa, if you think that you have not seen Kṛṣṇa, so Kṛṣṇa is present by His word also, Bhagavad-gītā. That is vāṇī, kṛṣṇa-vāṇī.
(Lecture on Srimad Bhagavatam----3:25:15).

So this is called faith. The faith is not blind. There is proof. He, the cobbler was not blindly believing that Nārāyaṇa was pulling an elephant through the hole of an needle, but he sees practically the potency, the power of the Lord, bījo 'haṁ sarva-bhūtānām (Bg 7.10), how He keeps all the potencies of the banyan tree within the seed. So otherwise there is no meaning, "all-powerful." He can do whatever He likes. Inconceivable. Śrīla Jīva Gosvāmī therefore explains that unless we believe (in the) inconceivable potency of the Lord, then we cannot understand that activities... Parāsya śaktir vividhaiva śrūyate, svābhāvikī-jñāna-bala-kriyā ca (Cc. Madhya 13.65, purport). We cannot judge how things are happening, but we have to believe. Therefore Vedic knowledge is so important. We cannot make research. We cannot judge. Simply if we take the Vedic truths... Just like we have several times explained, the Vedas accept the cow dung pure, whereas the stool of other animal is impure. So we have to accept like that. So Veda-vāṇī. Veda-vāṇī means you cannot deny it. You cannot argue on it. You have to accept as it is. Therefore learned scholar, when he speaks something, he gives evidence from the Vedas, śruti, śruti-pramāṇa. That is the best evidence.
(Lecture on the Nectar of devotion).

So now, by the grace of Kṛṣṇa and Caitanya Mahāprabhu and in the presence of my Guru Mahārāja, you are so nice boys and girls. So in front of Caitanya Mahāprabhu you are chanting Hare Kṛṣṇa mantra, and you are taking part in it very seriously. So my Guru Mahārāja will be very, very much pleased upon you and bless you with all benefits.
So he wanted this, and he is not... It is not that he is dead and gone. That is not spiritual understanding. Even ordinary living being, he does not die. Na hanyate hanyamāne śarīre (B.G.2:20). And what to speak of such exalted, authorized personality like Bhaktisiddhānta. He is seeing. I never feel that I am alone. Of course, when I came to your country without any friend, without any means... Practically, just like a vagabond I came. But I had full faith that "My Guru Mahārāja is with me." I never lost this faith, and that is fact. There are two words, vāṇī and vapuḥ. Vānī means words, and vapuḥ means this physical body. So vāṇī is more important than the vapuḥ. Vapuḥ will be finished. This is material body. It will be finished. That is the nature. But if we keep to the vāṇī, to the words of spiritual master, then we remain very fixed up. It doesn't matter. Just like Bhagavad-gītā. It was spoken five thousand years ago. But if you keep to the words of Kṛṣṇa, then it is always fresh and guiding. Not that because Arjuna personally listened to Kṛṣṇa about the instruction of Bhagavad-gītā, therefore he knew it. That is not the fact. If you accept Bhagavad-gītā as it is, then you should know that Kṛṣṇa is present before you in His words in the Bhagavad-gītā. This is called spiritual realization. It is not mundane historical incidences.
