Buddhism

I actually used some incense yesterday to try. But I'm not sure how long this one goes, so I will have to time it.

It's a bit more tricky to use it in the bedroom though, the smell is nice, but I can feel it in my eyes if there is not enough ventilation. I also find it quite difficult to notice that the smell is gone. But maybe that's something you learn.

Noticing that your body goes numb is quite a good way to notice too. But I feel like this is also something that changes over time. Nowadays I could sit for 1 hour without any discomfort or slumping, so it becomes a less reliable tell.

Something else that I've seen are these water clocks (if that's how you call them) Basically a pot of water that slowly drips into a bowl. It will make a dripping sound until the water is empty. So you can choose how long to meditate by filling the pot with the appropriate amount.

Now to figure out how to make something like that myself.
