We have tasted this material world. Everyone has tasted. It is full of miseries. Tri-tāpa yantraṇā. Tri means three, and tāpa means miserable condition of life. Tri-tāpa. Ādhyātmika, pertaining to this body and mind. Sometimes I am feeling some pain on my body, there is fever or some other ailment, the mind is not in order, this is called ādhyātmika. Similarly, ādhibhautika. Just like Pakistan is ready to attack us. If not Pakistan, then there are many other enemies; even there are many other living entities, just like mosquito, fly, bugs. So ādhibhautika, another living entity giving us trouble. And ādhidaivika—just like this famine, flood, pestilence, so many things which you cannot control.
So this is the position of this material world. Tri-tāpa yantraṇā trisura. You have seen the picture of Goddess Durgā—she is piercing the trisura on the chest of the asura, and he is suffering, his struggle for existence, fighting with the lion, rajo-guṇa. So this is the position of the material world and the certificate is given by Kṛṣṇa, the Lord Himself, that this place is duḥkhālayam aśāśvatam (BG 8.15). Duḥkhālayam, always full of miseries.
So the human form of life is meant for understanding what is my position. In the animal life we cannot understand that we are in a very, very miserable condition of life in this material world. Therefore Prahlāda Mahārāja says, mānuṣam, durlabhaṁ mānuṣaṁ janma, tad apy adhruvam. It will not stay. You can say: "All right, there is suffering. Let me suffer for some time. I shall get next life again or I shall be finished." But Prahlāda Mahārāja says: "Why do you think like that? Why you want to die like cats and dogs? Just acquire the benefit which you can have in this human form of life, Kṛṣṇa consciousness." Mānuṣam. Durlabhaṁ mānuṣaṁ janma, tad apy adhruvam. Although it will not stay, but it is arthadam. Arthadam means you can achieve the highest goal of life.
