"To become advanced in Kṛṣṇa consciousness, the first principle is smartavyaḥ satataṁ viṣṇu, 'Always remember Viṣṇu, or Kṛṣṇa.' That is the beginning, to touch. Vismartavyo na jātucit, 'never forget.' So this Hare Kṛṣṇa mahā-mantra, if you chant, there is no expenditure, but the profit is very, very great, because you are touched in Kṛṣṇa, and Kṛṣṇa and Kṛṣṇa's name nondifferent, identical. Nāma cintāmaṇiḥ kṛṣṇaś caitanya-rasa-vigrahaḥ, pūrṇaḥ. It is not that partial; pūrṇaḥ, because the name is of the pūrṇaḥ. Pūrṇasya pūrṇam ādāya pūrṇam evāvaśiṣyate (Īśopaniṣad Invocation). This is the Vedic version.
So it is not very difficult. Simply try to be in touch with the vibration. Where is the wrong there? What is the loss there? If you chant, just like these boys, they..., you have seen the picture, they have taken it seriously. They are working in the field: Hare Kṛṣṇa. They are working in the factory, of incense factory: Hare Kṛṣṇa. Where is the wrong there? Why India is not taking this? If you work in your factory, if you chant Hare Kṛṣṇa, then what is the loss there? But you remain always in touch with Kṛṣṇa, smartavyaḥ satataṁ viṣṇur. This formula is... We shall talk so many nonsense things, but you are not, I mean, desiring to chant Hare Kṛṣṇa. This is our fault. Otherwise Kṛṣṇa is so kind. Nāma rūpe kṛṣṇa avatāra. Kṛṣṇa is now descended in His vibration form, Hare Kṛṣṇa, this Kali-yuga. Kali-yuga, because we cannot do anything, therefore Kṛṣṇa has become very easily available in the form of His holy name, Hare Kṛṣṇa. Kṛṣṇa is available. You can see Kṛṣṇa, you can touch Kṛṣṇa, you can talk with Kṛṣṇa. As you may advance in Kṛṣṇa consciousness, that is possible. Then, gradually making progress means gradually you will be lover of Kṛṣṇa. That is required. Mayy āsakta, as soon as you become lover, you become attached. That is required.
Now, at the present moment, we are attached to so many things, because we have forgotten Kṛṣṇa. Now gradually, if you increase your attachment for Kṛṣṇa, then you will forget all these material. That is liberation. That is liberation. Bondage means we are becoming more and more attracted with this material world, and on account of this attraction, we have to accept another body, material body. And as soon as you accept a material body, you become under the control of this material nature. Liberation means to be freed from the control of the material nature.
It is a great science. Try to understand. Therefore it is said, jñānaṁ te 'haṁ sa-vijñānam. It is not sentiment. It is not religious sentiment. It is a science. Kṛṣṇa consciousness means to understand the science of Kṛṣṇa. We are understanding so many subject matters scientifically, but we are neglecting one thing: how to understand Kṛṣṇa scientifically. That science is described here, jñānaṁ te 'haṁ sa-vijñānam. Jñānaṁ te 'haṁ sa-vijñānam ahaṁ vakṣyāmy aśeṣataḥ yaj jñātvā (BG 7.2). If you simply try to understand the science of Kṛṣṇa, then all other sciences will be automatically understood. Just like if you understand what is one, two, three, four, five, six, seven, eight, nine, zero, then you understand the whole mathematical science, because the mathematics means that one, two, three, four, five, six, this way, that way, this way, that way. The only..., the figures are all, the digits are the one, two, three, four. So therefore one has to learn one, two, three, four, up to nine, and zero. Similarly, if you understand Kṛṣṇa, the indirectly and directly, everything is Kṛṣṇa. That is the highest scientific understanding of everything. That is a fact. Kṛṣṇa is earth, Kṛṣṇa is water, Kṛṣṇa is air, Kṛṣṇa is fire, Kṛṣṇa is sky, Kṛṣṇa is mind, Kṛṣṇa is intelligence, Kṛṣṇa is ego and Kṛṣṇa is soul. So this is required, jñānaṁ te 'haṁ sa-vijñānam."
