Some people have the idea that Kundalini Yoga is easy. This is true in one sense and very untrue in another.
It's true because we are most often sitting in easy pose and not jumping into chaturanga or kicking into handstand.
It's not true because we have many extremely pressurized exercises -- holding our arms up for 11 minutes or more, for example.
These exercises are part of the reason Kundalini Yoga works for me. Granted, I'm not excited when I'm the student and one of these comes up. I go through a whole mental process in those 11 minutes. It can start with discouragement (sometimes internal cursing). Then...
Sometimes we see only obstacles. I'm too tired. I'm too stiff. I'm overweight. I'm injured. But the truth is there's always a way. There's always a modification. There's always a benefit to being in a yoga class.
I met a woman earlier this year who exemplifies this. She had chronic fatigue syndrome, but something in her told her to go to yoga. She did not have the energy to do any of the poses or to even sit upright, so she slept through each class. I'll repeat that: she slept through each class. FOR. A. YEAR.
