Regretting, lamenting, "My Lord, I got this human form of life. Unfortunately I have simply wasted." Why? Rādhā-kṛṣṇa nā bhajiyā manuṣya-janama pāiyā, rādhā-kṛṣṇa nā bhajiyā. "It is exactly like drinking poison knowingly." Sometimes we become poisonous unknowingly—sometimes food poison or something poison. But if one takes poison knowingly, that means he's killing himself. He knows it. Similarly, in this human form of life, if we do not come to this understanding, sahasā vipaścit, that "Without Kṛṣṇa consciousness, I am simply taking poison," then his life is spoiled. Gata-smṛtir vindati tatra tāpān. He will simply be put into miserable condition. That is the nature's way, daivī hy eṣā guṇamayī mama māyā dur . . . (BG 7.14). You cannot escape the stringent laws of material nature. You will go on suffering, suffering. Mṛtyu-saṁsāra vartmani (BG 9.3). You will suffer again and again, this body and next body, next body. That is nature's way. But ahaṅkāra-vimūḍhātmā kartāham iti manyate (BG 3.27). These rascals, on account of false prestige, false knowledge, false education, he is thinking that "I am independent. I can do what ever I like," ahaṅkāra-vimūḍhātmā kartāham (BG 3.27). We have to give up this. Then vipaścit, sahasā vipaścit. Otherwise we have to continue the miserable condition of life. Gata-smṛtiḥ: because we have forgotten our real position.
What is our position? Our position is as described by Caitanya Mahāprabhu, jīvera svarūpa haya nitya-kṛṣṇa-dāsa (CC Madhya 20.108-109). Our real position is that I am eternal servant of Kṛṣṇa. So gata-smṛtiḥ, I have forgotten that. And therefore, bhuliyā tomāre saṁsāre āsiyā peye nānā-vidha byathā. Bhaktivinoda Ṭhākura's song, "My Lord, forgetting You, I came in this material world. I am simply suffering."
