My meditation practise has ranged from being very erratic to very consistent and I have only done breath and meththa meditation.
Meththa meditation,has ALWAYS allowed the following mental states to arise in me:
-Softness, calmness, some sense of joy, some sense of peace, a positive outlook about myself and the rest of the world, ease to sleep at night
Breath meditation has SOMETIMES brought about the following mental states:
-Concentration. Feelings of very disproportionate, often elongated proportions of my body. When I am in a typical sitting meditating position, I sometimes feel the distance between my nose and my palms/foot area is so very LOOOOOOOOOOONG. Sometimes I feel like I am like a HUGE GIANT. Also mental vibrations, as in, the visual I get when I close my eyes tends to vibrate gently at first and then increases in frequency and in magnitude to a scary level. I haven't gone beyond this stage. When I open my eyes after such a state, my vision with my eyes OPEN also tends to vibrate but soon returns to normal though.
No meditation has ever brough me bliss or jhana. I have an increased sensitivity to read other people's very subtle facial expressions.
