So His energy is working even in the water. You can perceive His energy within the water. We are daily using water. We are tasting water. So you can perceive Kṛṣṇa's presence, Kṛṣṇa's all-pervasiveness, even while you drink water. Every one of us, we drink water. And... So the taste of the water, Kṛṣṇa says, "Here I am." This is impersonal feature, but the person is behind. Mayādhyakṣeṇa prakṛtiḥ (BG 9.10). Water is one of the products of this material nature, but behind this existence of water is Kṛṣṇa. Then you can understand Kṛṣṇa. You try to understand by studying His energy. Therefore Kṛṣṇa is describing that "Although you cannot see Me just now..." Because in the preliminary stage nobody can see Kṛṣṇa, although Kṛṣṇa is present everywhere. Aṇḍāntara-stha-paramāṇu-cayāntara-stham (Bs. 5.35). He is present within the atom. But it requires the qualified eyes to see Him or purified senses to perceive Him.
That is stated in the śāstra: ataḥ śrī-kṛṣṇa-nāmādi na bhaved grāhyam indriyaiḥ (CC Madhya 17.136). With our these present senses we cannot understand what is the holy, transcendental name of Kṛṣṇa. Therefore sometimes we are misunderstood, that "Why these people are chanting Hare Kṛṣṇa?" So... Because ordinary man or ordinary senses cannot understand the value, the nature of the name, therefore śāstra says, ataḥ śrī-kṛṣṇa-nāmādi. Nāmādi, beginning from name. We can realize God by chanting name. Because abhinnatvān nāma-nāminoḥ. Nāma cintāmaṇiḥ kṛṣṇaś caitanya-rasa-vigrahaḥ (CC Madhya 17.133). These are the description of the śāstras. Nāma, the holy name of the Lord, is completely spiritual. Nāma cintāmaṇiḥ kṛṣṇa. He is... Nāma is, name is as good as Kṛṣṇa. Nāma cintāmaṇiḥ kṛṣṇaś caitanya-rasa-vigrahaḥ. Those who are chanting Hare Kṛṣṇa mahā-mantra without any offense, they are tasting spiritual nectarine. Just like Rūpa Gosvāmī has written a śloka that "If I could possess millions of ears and millions of tongues, then I could enjoy what is the transcendental mellow in chanting Hare Kṛṣṇa mahā-mantra. But that is not possible for ordinary human being in the beginning. Therefore śāstra says, ataḥ śrī-kṛṣṇa-nāmādi na bhaved grāhyam indriyaiḥ (CC Madhya 17.136). These impurified senses cannot appreciate the value of the holy name of Kṛṣṇa. Nāma-ādi, His name, His quality, His pastimes, His form, His activities... There are so many things, beginning with nāma, Hare Kṛṣṇa mahā-mantra. As we go on chanting, Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma ,Rāma Rāma, Hare Hare, and as we become purified... The more we chant, we become purified.
