God has given advanced consciousness to the human being. Therefore he can feel the suffering and happiness of other living beings. The human being bereft of his conscience, however, is prone to cause suffering for other living beings. The assistants of Yamarāja put such a person into the hell known as Andhakūpa, where he receives proper punishment from his victims.
(Srimad Bhagavatam----5:26--summary).

By the arrangement of the Supreme Lord, low-grade living beings like bugs and mosquitoes suck the blood of human beings and other animals. Such insignificant creatures are unaware that their bites are painful to the human being. However, first-class human beings—brāhmaṇas, kṣatriyas and vaiśyas—are developed in consciousness, and therefore they know how painful it is to be killed. A human being endowed with knowledge certainly commits sin if he kills or torments insignificant creatures, who have no discrimination. The Supreme Lord punishes such a man by putting him into the hell known as Andhakūpa, where he is attacked by all the birds and beasts, reptiles, mosquitoes, lice, worms, flies, and any other creatures he tormented during his life. They attack him from all sides, robbing him of the pleasure of sleep. Unable to rest, he constantly wanders about in the darkness. Thus in Andhakūpa his suffering is just like that of a creature in the lower species.
(Srimad Bhagavatam----5:26:17----translation).

A person who steals another's money, wife or possessions is put into the hell known as Tāmisra. A man who tricks someone and enjoys his wife is put into the extremely hellish condition known as Andhatāmisra. A foolish person absorbed in the bodily concept of life, who on the basis of this principle maintains himself or his wife and children by committing violence against other living entities, is put into the hell known as Raurava. There the animals he killed take birth as creatures called rurus and cause great suffering for him. Those who kill different animals and birds and then cook them are put by the agents of Yamarāja into the hell known as Kumbhīpāka, where they are boiled in oil. A person who kills a brāhmaṇa is put into the hell known as Kālasūtra, where the land, perfectly level and made of copper, is as hot as an oven. The killer of a brāhmaṇa burns in that land for many years. One who does not follow scriptural injunctions but who does everything whimsically or follows some rascal is put into the hell known as Asi-patravana. A government official who poorly administers justice, or who punishes an innocent man, is taken by the assistants of Yamarāja to the hell known as Sūkaramukha, where he is mercilessly beaten.
(Srimad Bhagavatam----5:26--summary).

There is actually only one religious principle: dharmaṁ tu sākṣād bhagavat-praṇītam [SB 6.3.19]. The only religious principle is to follow the orders of the Supreme Personality of Godhead. Unfortunately, especially in this age of Kali, everyone is an atheist, people do not even believe in God, what to speak of following His words. The words nija-veda-patha can also mean "one's own set of religious principles." Formerly there was only one veda-patha, or set of religious principles. Now there are many. It doesn't matter which set of religious principles one follows: the only injunction is that he must follow them strictly. An atheist, or nāstika, is one who does not believe in the Vedas. However, even if one takes up a different system of religion, according to this verse he must follow the religious principles he has accepted. Whether one is a Hindu, or a Mohammedan or a Christian, he should follow his own religious principles. However, if one concocts his own religious path within his mind, or if one follows no religious principles at all, he is punished in the hell known as Asi-patravana. In other words, a human being must follow some religious principles. If he does not follow any religious principles, he is no better than an animal. As Kali-yuga advances, people are becoming godless and taking up so-called secularism. They do not know the punishment awaiting them in Asi-patravana, as described in this verse.
(Srimad Bhagavatam----5:26:15----purport).

Those who in this life confine other living entities in dark wells, granaries or mountain caves are put after death into the hell known as Avaṭa-nirodhana. There they themselves are pushed into dark wells, where poisonous fumes and smoke suffocate them and they suffer very severely.
(Srimad Bhagavatam----5:26:34----translation).

A thief is put into the hell known as Sandaṁśa.
(Srimad Bhagavatam----5:26--summary).

My dear King, a person who in the absence of an emergency robs a brāhmaṇa—or, indeed, anyone else—of his gems and gold is put into a hell known as Sandaṁśa. There his skin is torn and separated by red-hot iron balls and tongs. In this way, his entire body is cut to pieces.
