Zazen, left brain, right brain, self

During the last COVID wave, while activities were restricted and I was largely staying at home, I intensified my zazen (sitting meditation) practice. With more attention to my  practice, I was surprised to find I was easily sitting for 45 minutes and spending less of that time lost in thoughts and more time simply being present here-now aware of the arising and passing on random thoughts, sensations and sensory inputs.

There are four main categories of things that distract my attention from being here-now:

  • Largely verbalised thought sequences. These can be somewhat spontaneous, jumping across subjects and concerns, or more focused on solving a problem, thinking through a situation or piece of work to be done, planning, strategizing, worrying, pondering the past or future.
  • Distracting sensory stimuli with associated thoughts and emotions, eg. An intrusive noise, an insect flying around or crawling on my skin, an itch, or an ache or pain.
  • Images that appear in the minds eye. These can be random or connected.
  • Full-blown dream-like visions or daydreams, sometimes short, sometimes long.

I also occasionally experience auditory or olfactory hallucinations. For example, a voice saying something, or a distinct smell.  But these are rare.

One of the best things on TV.  On this particular episode, a mystery guest Charlotte came onto the show, and each member of one team had to explain how they knew Charlotte.  Joe Lycett claimed that “In the evenings, I like to relax by watching videos of her wrapping gifts on YouTube. “

It turned out to be true. Afterwards, I looked up Charlotte on YouTube and found a video of her wrapping presents.

Brainwave entrainment

The basic idea of brainwave entrainment is to use an external periodic stimulus to cause wave1brainwave frequencies to fall into step with it at a frequency corresponding to the intended brain-state (for example, to induce sleep or meditative states). There is good evidence that the human brain has a tendency to change its dominant EEG frequency towards the frequency of a dominant external stimulus. Such a stimulus may be aural, as in the case of binaural or monaural beats and isochronic tones,or light (visual), or a combination of the two with a mind machine.
