Complicated meditation, I am not asking you to do any of it, am I?
A lot of these meditations ask you to do any or all of these, and I do not recommend any of it. According to me,
No closed dark room is required
No need to close your eyes
No need to chant anything
No need of any photo
You can do exactly the opposite in fact,
Sitting in open spaces
Open your eyes and be aware of what's happening around you
Keep an open free mind
No more than one hour to the max
