Prabhupada's lecture - Śrīmad-Bhāgavatam 1.8.44 - Māyāpura, October 24, 1974
So the baby, packed up, cannot move, cannot say anything but feels pain, therefore moves. And the pregnant woman therefore feels that the child is moving at the age of seven months in the womb. So therefore the struggle begins from the womb. And when the child comes out, again struggle. And he is lying on the bed; some bug is biting. He cannot express. He is crying, and the mother thinks that he's hungry. In this way, wrongly understands, cannot give relief him. And he is going on, crying, crying, crying. We have seen it. We have... Everyone has got experience.
Then as soon as he is grown up, he is given responsibility for learning ABCD, or going to school. He doesn't like. No child likes. At least I did not like to go to school. So this is also another struggle. Then, when he is grown up, he is given more and more responsibility, examination, and then married life, then family maintenance. In this way, struggling, struggling, struggling—again death. Again enter into the womb of mother. Again the same struggle. So where is happiness? Therefore when Kṛṣṇa says, duḥkhālayam aśāśvatam: [Bg. 8.15] "This whole material world is a place for suffering only," that is a fact. But mūḍho 'yam, being enamored by māyā, he does not know. He forgets. This life is of forgetfulness, ignorance.
