One of the basic tenets of yoga is chitta vriti nirodha. Basically, it means that the practice of yoga stops the endless cycle of thoughts for clarity of mind.
This might have subconsciously influenced me, but I often ask friends who I haven't seen in a long time, or friends who are going through a hard time, to name the top three things they are thinking about.
For me, right now, they are the following:
1)Certain situations in my family
2)Moving to India
I think we are wired to let our minds spin around and around just a couple of recurring topics until we get frustrated or obsessed. Like how many times have I thought about going to the gym today, or planned what will fit in my backpack for Indicorps.
In any case, it is fascinating to step outside of yourself for a second to see what's going on in your head. Maybe I should make some space for new ideas.
