If you want to make a solution of material existence by the material way, it is not possible. That is also clearly stated. In the Bhagavad-gītā you'll find, daivī hy eṣā guṇamayī mama māyā duratyayā (BG 7.14). This material nature which is accepted, claimed by Kṛṣṇa as "My energy," mama māyā... This is also another energy of Kṛṣṇa. Everything will be explained in the Seventh Chapter. So it is very difficult to get out of this energy. Practically we are seeing what we are. Our efforts are very tiny to conquer over the laws of the material nature. It is simply waste of time. You cannot become happy by conquering over the material nature. Now science have discovered so many things. Just (as) the airplane from India. It would have taken months together to reach your country, but by airplane we can come here overnight. These advantage are there. But along with these advantages, there are so many disadvantages. When you are on the plane on the sky, you know you are in the midst of desert..., of danger. At any moment there can be crash. You may fall down on the sea, you may fall down anywhere. So it is not very safe. So similarly, any method we manufacture, we discover, to conquer over the laws of material nature, it is backed by another set of dangerous things. That is the law of nature. That is not the way to get out of this material pangs of life.
The real way is to stop these four functions of my conditional life. The four functions of conditional life means birth, death, old age, and disease. Actually, I am a spirit soul. That is explained in the beginning of Bhagavad-gītā, that the spirit soul is never born or is never dead. He continues his life even after the destruction of this particular type of body. This body is only a flash, for some years only. But it will be finished. It is being finished by degrees. Just like I'm an old man of seventy-three years old. Suppose if I live eighty years or a hundred years, these seventy-three years I have already died. That is finished. Now a few years I may remain. So we are dying from the date of our birth. That is a fact. So Bhagavad-gītā gives you the solution of these four problems. And Kṛṣṇa here is suggesting, mayy āsakta-manāḥ pārtha yogaṁ yuñjan mad-āśrayaḥ. If you take shelter of Kṛṣṇa and if you think of Kṛṣṇa always, your consciousness becomes always overwhelmed with Kṛṣṇa thoughts, then Kṛṣṇa says the result will be asaṁśayaṁ samagraṁ māṁ yathā jñāsyasi tac chṛṇu (BG 7.1). "Then you will understand Me perfectly, without any doubt."
