A very detailed description of the various Narak lokas are given here. What karma leads you to each one of them?

Read it yourself and get bewildered. So, we will not mention them here.

Note : We are not giving a detailed explanation of the slokas here, as it is a very direct message. Usually we can see the warnings of punishment by sentencing one to the hell in semantic religions.

Why Bhagavatham gives a similar warning to us? Because fear diverts the mind faster than wisdom.

A vulnerable mind that seeks sensual pleasure is not wise and can yield to any temptations easily. It will be very difficult to stop such a person from committing mistakes. There, fear of punishment and the consequent suffering diverts his mind immediately to wisdom.

But, we must understand that a mind gripped by fear constantly cannot experience joy either.

Heaven and Hell are the creations of your own mind and hence you can experience it here and now. The unfathomable law of Karma is established in this part of Bhagavatham.
