Purify the tongue by chanting and Prasadam-Krsna will reveals himself

Nod vrn oct 26 72
You cannot see God, you cannot see Kṛṣṇa by your, these blunt senses, but if you purify your senses, sevonmukhe hi jihvādau. That purification begins from tongue. That purification, sevonmukhe hi jihvādau. So by the tongue we can do two things. We can taste foodstuff and we can vibrate sound. So if you engage your tongue for vibrating this transcendental sound, Hare Kṛṣṇa Hare Kṛṣṇa Kṛṣṇa Kṛṣṇa HareHare/Hare Rāma Hare Rāma Rāma Rāma Hare Hare, and do not take anything except prasādam of Kṛṣṇa, then your spiritual life immediately begins. Sevonmukhe hi jihvādau, svayam eva... Then gradually, as you advance in spiritual life, Kṛṣṇa reveals Himself to you, "Here I am." You cannot see Kṛṣṇa, but by being satisfied with your service, Kṛṣṇa sees you. Just like you cannot see sun at night. But when the sun sees you, you can see the sun and yourself, both. Similarly, when Kṛṣṇa sees you, being satisfied with your service, then you can see Kṛṣṇa, you can see yourself and you can see the whole world.
Now, whatever you are seeing, this is all illusion. You are not seeing, or we are not seeing. Because our senses are blunt to see things as they are. Therefore in the Bhagavad-gītā it is said that
vidyā-vinaya-sampanne
brāhmaṇe gavi hastini
śuni caiva śva-pāke ca
paṇḍitāḥ sama-darśinaḥ
[Bg. 5.18]
One who has got the eyes to see, he does not see that "Here is a learned brāhmaṇa, and here is a dog." He sees both the learned brāhmaṇa and the dog in equal vision. Because he does not see the dress. He sees the spirit soul within the brāhmaṇa and within the dog. That is calledbrahma-darśana. Samaḥ sarveṣu bhūteṣu. Mad-bhaktiṁ labhate parām[Bg. 18.54]. When one has got that vision, transcendental vision, samaḥsarveṣu bhūteṣu mad-bhakti, then the devotional service begins. Not that with blunt eyes and senses one can serve God, devotional service.
