Goal of liberation in yoga/meditation - Isn't it Boring? I see that the goal of yoga/meditation is liberation from the karma and from the birth/death cycle. People say that it is the ultimate happiness forever. But wouldn't that be boring and monotonous if there is happiness forever?
In Buddhism, Nibbana refers to liberation from suffering (dukkha). It is also referred to as the highest bliss (nibbanam paramam sukham) in Dhp 204. The word sukha is translated in this context as bliss, but in other contexts, also as happiness.

Boredom is a type of suffering. An enlightened person is free from this type of suffering too.

We have 3 types of feelings - pleasant feelings (usually associated with sensual enjoyment), painful feelings (usually associated with aversion) and neither-pleasant-nor-painful feelings (usually associated with boredom and confusion). Feelings here include forms with eyes, sound with ears, odor with nose, taste with tongue, touch with body and ideas with mind.

When an unenlightened person experiences neither-pleasant-nor-painful (or neutral) feelings, he may experience boredom. But when an enlightened person experiences neutral feelings, he experiences bliss.

So, is unending happiness or bliss a source of boredom? Not for the enlightened one.

What causes boredom?

The neither-pleasant-nor-painful feelings also known as neutral feelings, normally make us bored or dissatisfied. Cravings (tanha) would lead one to seek pleasures (kama tanha) or to become something or achieve something (bhava tanha) rather than sit around all day experiencing neutral feelings that don't bring satisfaction. No feelings at all, would also be a cause for boredom and dissatisfaction. 

The first noble truth states that there is suffering.

The second noble truth states that the cause of suffering is craving. This includes the suffering of boredom too.

The third noble truth states that with the cessation of craving, comes the cessation of suffering. This includes the cessation of boredom too.

The fourth noble truth shows the path to end suffering, which is the noble eightfold path.
