So, this Kṛṣṇa consciousness movement, it is nothing of this material world. This Hare Kṛṣṇa mantra, it is also not any vibration of this material world. There is a verse by Narottama dāsa Ṭhākura, golokera prema-dhana hari-nāma-saṅkīrtana. This hari-nāma-saṅkīrtana is vibration from the spiritual world. Just like you receive some message, vibration of the material world, from Europe, from America. So that is not Indian vibration but American vibration or European vibration. Similarly, there is vibration in the spiritual world. Simply one has to catch. You must have that machine. So, that machine is there within you. The heart is the machine where you can receive the spiritual message, because within the heart there is Nārāyaṇa. Īśvaraḥ sarva-bhūtānāṁ hṛd-deśe. Particularly it is mentioned, hṛd-deśe. So because Nārāyaṇa, or īśvara, is situated within the heart of everyone, there is no necessity of researching where is Nārāyaṇa. The śāstra says it is within your heart. Therefore the yogis, they practice yogic rocess how to see Nārāyaṇa within the heart. Dhyānāvasthita-tad-gatena manasā yaṁ paśyanti yogino. The yogic process is to see Nārāyaṇa within the heart. Similarly, you can hear also Nārāyaṇa by this transcendental vibration. He can be perceived, because we have got senses, different senses. We can see, and we can hear also. Because the Supreme Personality of Godhead is Absolute Truth, by any of your senses, either by seeing or by hearing, it is the same thing. Nāma cintāmaṇiḥ kṛṣṇaś caitanya-rasa-vigrahaḥ. Rasa-vigrahaḥ. Nāma, this name, holy name of Kṛṣṇa or holy name of Rāma, they are rasa-vigrahaḥ, transcendental blissful form. That is also... Vigraha means form. That form is understood through the ear, and it goes to the heart. In this way we can perceive Nārāyaṇa by chanting Hare Kṛṣṇa mahā-mantra. It requires little practice, as they are enunciated in the śāstras and directed by the spiritual master. Then one can understand, or one can see. Just like, premāñjana-cchurita-bhakti-vilocanena santaḥ sadaiv hṛdayeṣu viloka, the same thing hṛdayeṣu. As it is stated in the Bhagavad-gītā, īśvaraḥ sarva-bhūtānāṁ hṛd-deśe arjuna tiṣṭhati. Similarly, the same thing is stated there in the Vedic literature. Bhagavad-gītā is also Vedic literature, Brahma-saṁhitā. Premāñjana-cchurita-bhakti-vilocanena santaḥ sadaiva hṛdayeṣu vilokayanti. Same, the same thing hṛdā.
So, anyone can see God within his heart, if he adopts the process, bona fide process. Nārāyaṇa is within you. Therefore, great, great saintly persons, they are sitting in a lowly place, alone. But he is not alone. He is with Nārāyaṇa, Kṛṣṇa. He is seeing always there. So he is not alone. We are always accompanied by the Supreme Personality of Godhead as paramātmā, antaryāmī, within the heart. That is the Vedic statement, that there are two birds sitting on the same tree. One bird is enjoying the fruit of the tree, and the other bird is simply witnessing. So the two birds, jīvātmā and paramātmā, are always associated. He is so kind, He is just looking forward, "When this jīvātmā, who is illusioned, bewildered, captivated by this material world, material enjoyment, when he will come back again to Me?" Just like father and the son, the son who has gone out of home. The father is always looking forward when the son would come back at home and enjoy. Similarly, Kṛṣṇa, the supreme father, He is always looking forwad when we shall go back to Him. Therefore, He comes personally, yadā yadā hi dharmasya glānir bhavati bhārata, tadātmānaṁ sṛjāmy aham. The general opportunity for human being is to understand God, or Kṛṣṇa, and go back to Him again. We have come from Him, but we are attracted by this material enjoyment, which is not very pleasurable. It is suffering. Just like here, without this fan, it was uncomfortable, excessive heat. So, excessive heat, excessive cold, so many things, adhibautic, adhyatmic, adhidaivic. We are actually suffering always. This is the nature of this material world. Stringent laws of the material world. And still we are trying to become happy by some adjustment. This is called struggle for existence. In this way we cannot be happy.
