Hare Kṛṣṇa sound is transcendental. That's all right. But if you don't like Hare Kṛṣṇa sound, you take any sound, any sound is also . . . that is coming from the original sound; simply it is covered by māyā. What is the difference between spiritual and material? Everything is spiritual. Sarvaṁ khalv idaṁ brahma (Chāndogya Upaniṣad 3.14.1). But when it is covered by māyā, it is material. That's all. And what is māyā? Forgetfulness of Kṛṣṇa. The same water, the same water, it is spiritual, because it is Kṛṣṇa's energy. Kṛṣṇa has already said, bhūmir āpaḥ. Āpaḥ. Here also, apsu. So āpaḥ, jala, or water, is Kṛṣṇa's energy. How it can be different from Kṛṣṇa? So we have to deal with water in so many ways. How we can forget Kṛṣṇa?
The Kṛṣṇa consciousness movement is the spreading the knowledge of Bhagavad-gītā as it is. So how one can become Kṛṣṇa conscious very easily without any loss, but gain is very much—why don't you take this advantage of Kṛṣṇa consciousness movement? What is the reason that you'll not take? Satataṁ kīrtayanto māṁ yatantaś ca dṛḍha-vratāḥ (BG 9.14). If you become Kṛṣṇa conscious in this way, the profit is very, very great. Because the more you become Kṛṣṇa conscious, the more Kṛṣṇa becomes revealed to you. Sevonmukhe hi jihvādau svayam eva sphuraty adaḥ. Realization, revelation, that . . . with the blunt senses you cannot understand Kṛṣṇa, you cannot realize Kṛṣṇa. But if you purify . . . ataḥ śrī-kṛṣṇa-nāmādi na bhaved grāhyam indriyaiḥ (CC Madhya 17.136). Our present senses are blunt senses because it is covered by forgetfulness of Kṛṣṇa, or māyā. Therefore it has to be purified. Or the nature of forgetfulness has to be removed. That's all. This is the process. Raso 'ham apsu kaunteya (BG 7.8). If you follow this process, that "Here is drinking water, the taste is Kṛṣṇa," that means some percentage of your forgetfulness of Kṛṣṇa is removed. Similarly, when you see the sunshine, the moonshine, or you chant oṁkāra . . . there are other, so many ways prescribed in the later verses. So try to understand Kṛṣṇa in this way. It doesn't require any advancement of education or Vedic knowledge. A simple thing.
