Simple breath meditation - focusing on and slowing the breath. No need to complicate it.

Bringing the wandering attention back, over and over to the breath while gradually slowing the breath from 6-8 breaths/minute to 2 breaths/minute. Slowing the breath down to that level, ime, allows you to delve deeper and deeper with ease. Deep from the belly breaths.

This practice ime has given me the most benefit. Thoughts eventually thin out, one by one; more and more light comes about, complete body loss as you go deeper; eventually, there is no thoughts, no "I"; just experience. Like an onion. Eventually - the thinker - the you - becomes suspended; unhinged from it's faculties, sinking deeper and deeper into the ever-moving stillness.
