Kṛṣṇa's another name is Vaikuṇṭha, or God's another name is Vaikuṇṭha. Vaikuṇṭha means vigata-kuṇṭha hy asmāt. Therefore spiritual world is called Vaikuṇṭha. And the material world is duḥkhālayam aśāśvatam (BG 8.15). It is not Vaikuṇṭha. You cannot even walk without anxiety. Just like we were walking on the street, and the leg slipped. So we should be very much careful even in walking. Beginning from your morning walk, you are full of anxiety. But Vaikuṇṭha means no anxiety. No anxiety. That is spiritual world. We must understand what is Vaikuṇṭhaloka and what is Jaḍaloka.
So here, everywhere simply danger. But if we take shelter of the Vaikuṇṭha, Kṛṣṇa . . . samāśritā ye pada-pallava-plavam (SB 10.14.58). It is just like the boat for crossing over a furious, dangerous ocean. Kṛṣṇa's lotus feet is compared with very sound, secure boat. And boarding it, you can cross over the ocean of nescience. Bhavāmbudhir vatsa-padam. Bhavāmbudhiḥ. Ambudhi means sea, and bhava means repetition of birth and death, birth and death. Just like in the ocean you are struggling. Sometimes you are drowning, and somebody helps you, saves you from being drowned, and again he throws you in the ocean. Then again struggle. So our life in this material world is like that. We are struggling from the beginning, very beginning of our life. We are simply struggling.
