Kṛṣṇa said that this material life is duḥkhālayam, simply full of miseries. But under the spell of māyā we are thinking that we are very happy. That's not the fact. Therefore human life is a chance to get out of this miserable condition. That should be the aim of life: how to get out of this miserable condition of life. That requires knowledge how we are suffering, how it can be mitigated. The sufferings will be ended . . . The same thing: unless you become law-abiding to the laws given by God, you'll suffer. That is nature's way. The same principle: unless you become lawful, the police will give you punishment. Similarly, material nature, that is explained in Bhagavad-gītā, puruṣaḥ prakṛti-stho 'pi bhuṅkte tad-guṇān (BG 13.22). We are suffering because in the material there are threefold miseries generally: adhyātmika, adhibhautika, adhidaivika. That is permanent. Besides that, extra miserable condition due to the age, due to the climate, due to the condition of life. So we have to study these things. Why . . . This human life begins when he begins to say "Why?" Keno . . . (indistinct) . . ., "Why we are suffering?"
So there are different methods how to get out of the suffering condition, karmī, jñānī, yogī. But ultimate, very easy process is, if you become a devotee, if you become engaged in Kṛṣṇa consciousness, then it is very easy. Kṣemo 'kuto-bhayaḥ (SB 6.1.17). Then your prosperity, your auspicity, is guaranteed.
