Four Noble Truths - Suffering 2

sdug bsngal, suffering, is by the way dukkha in Sanskrit. There are three basic ones, of which this one is the first one, sdug bsngal gi sdug bsngal, suffering of suffering.
This is the normal suffering, pain, headaches, stiff back, bad teeth, and so on. If someone has a samsaric body, one gets samsaric sufferings, that's for sure.

This is also a good grammar lesson, the middle particle, gi, is a genitive particle, it binds the right side element with the left one, with grammar particles, usually look from the right to the left. Here it does not really matter, but with other constructs it's good to make the right to left binding, otherwise the translation is wrong.

Also note that the grammar particle differs based on the last syllable in the first word, as it's la, the binding grammar particle takes the form of gi.
