Then the question is that "If I am eternal, why there are so many miserable condition of life? And why I am forced to die?" So this is actually the intelligent question, that "If I am eternal, then why I shall remain in this material body which is subjected to death, birth, old age and disease?" Therefore Kṛṣṇa instructs that this miserable condition of life is due to this material body. Those who are karmīs, means those who are engaged in sense gratification... They are called karmīs. The karmīs do not care for future; they simply want immediate facilities of life. Just like a child without the care of the parents, he plays whole day and doesn't care for future life, do not take any education. But in the human form of life, if we are actually intelligent, we shall try our best how to get that life or body where there is no more death, birth, old age and disease.
So this Kṛṣṇa consciousness movement means to educate people for that purpose. Now, one may say that "If I simply devote in Kṛṣṇa consciousness, then how my material necessities will be supplied?" So the answer is there in the Bhagavad-gītā, that anyone who is simply engaged in Kṛṣṇa consciousness, for his necessities of life Kṛṣṇa will look after. Kṛṣṇa is looking after for everyone's maintenance. Eko yo bahūnāṁ vidadhāti kāmān: "That one Supreme Person is maintaining the necessities of all living entities." So for a devotee who is trying to go back to home, back to Godhead, there will be no scarcity. Be rest assured. Kṛṣṇa says in the Bhagavad-gītā, teṣāṁ satata-yuktānāṁ yoga-kṣemaṁ vahāmy aham: (BG 10.10) "A devotee who is engaged always in My service, I look after, how his necessities of life will be fulfilled." A practical example is that in this Kṛṣṇa consciousness movement we have got one hundred centers, and each temple, not less than twenty-five, up to 250 devotees live. So we have no fixed up means of income, and we are spending in all the branches eighty thousand dollars per month. But by grace of Kṛṣṇa we have no scarcity; everything is supplied. People are surprised sometimes that "These people do not work, do not take any profession, simply chant Hare Kṛṣṇa. How they live?" So that is no question. If cats and dogs can live at the mercy of God, the devotees can live very comfortably by the mercy of God. There is no such question, but if somebody thinks that "I have taken to Kṛṣṇa consciousness, but I am suffering for so many things," for them or for all of us the instruction is mātrā-sparśās tu kaunteya śītoṣṇa-sukha-duḥkha-dāḥ: (BG 2.14) "These pains and pleasure is just like winter and summer." In the winter the water is painful, and in the summer the water is pleasing. So what is the position of the water? It is pleasing or painful? It is neither painful, neither pleasing, but in certain season, by touching the skin it appears to be painful or pleasant. Such pains and pleasure is explained herein: "They are coming and going. They are not permanent." Āgama apāyinaḥ anityāḥ means "They are coming and going; therefore they are not permanent." Kṛṣṇa therefore advises, tāṁs titikṣasva bhārata: "Just tolerate." But you do not forget your real business, Kṛṣṇa consciousness. Don't care for these material pains and pleasure. Of course, we shall try our best if there is pains and pleasure to counteract it, but even it is not done, don't be misled by these so-called pains and pleasure.
