The devotees also go on pilgrimages to various temples, perform religious rituals, take a holy bath in the rivers and fast for a month, especially among women who believe fasting helps in their family's well-being or in getting them a good husband.

Ivar Rodningem is a professional illustrator, whose imaginative mind transports us into a parallel world where trolls roam the lands. These creatures might seem scary at first sight, but in reality they are very docile and friendly, help each other and humans that they happen to meet. One of their characteristic features is of course their large noses and long tails. They are one with the nature, which is why it is almost impossible to see a troll if he doesn’t want to be found. Just like you and I they love having fun, though it is hard thing to do, considering their size.
