So this materialistic way of life, without any knowledge of the outside world, or without any knowledge... Outside world means just like we are within this universe. It is covered. The round thing which we see in the sky, that is the covering. Just like a coconut shell. A coconut shell, within and without. Within the coconut shell it is darkness, and without it is light. Similarly, this universe is just like the coconut. We are within. As in within coconut there is water, half water, similarly, within this universe there is half water. On that water, Lord Viṣṇu, Garbhodakaśāyī Viṣṇu, is lying. And from His navel, a lotus stem is sprouted. Just imagine within the coconut there is water, and somebody's lying, and there is some stem out of the navel. Exactly this universe is like that. But outside the universe there is light. Here, within the universe, because it is covered, light is required. Sunlight is required. Moonlight is required. Electricity is required. But in the spiritual world there is no necessity of light. They're self effulgent. Therefore tamo 'ndham. Those who are actually serious about going out of this darkness and come to the light, tamasi mā jyotir gama: "Don't remain in this darkness. Come to the light."
So anyone who is very serious... Atititīrṣatāṁ tamo 'ndham. Those who are actually serious to go out of this darkness to light, for them this is the lamp. Just like in darkness, if you are helped with a lamp, "Please come this way. Come this way," so you can come out of the darkness. Similarly, atititīrṣatām, one who wants to get liberation from this darkness, for them this Śrīmad-Bhāgavatam is given by Śukadeva Gosvāmī. Saṁsāriṇām... Karuṇayā. This is the business of the saintly persons. They are very much compassionate to these materialistic men, saṁsāriṇām. Saṁsārī means they are perpetually rotating, wandering, within this darkness in different forms of life.
