Shikantaza, or "just sitting" meditation, is a core practice in Soto Zen Buddhism. It is a form of zazen, or seated meditation, that focuses on simply being present in the moment without any specific goal or object of concentration.

To practice shikantaza meditation, find a quiet and comfortable place to sit. You can sit on a cushion on the floor or on a chair, whichever is most comfortable for you. Keep your back straight, but not rigid, and your hands resting comfortably in your lap.

Once you are settled into your posture, close your eyes and take a few deep breaths to relax your body and mind. Then, simply allow your breath to flow naturally without trying to control it. This serves as an anchor for your attention, but you should not actively focus on your breath.

As you sit, thoughts, feelings, and sensations will arise. Instead of trying to push them away or engage with them, simply observe them with a sense of detachment. Imagine them as clouds passing by in the sky, or leaves floating down a stream. Allow them to come and go without getting caught up in them.

If you find yourself getting lost in thought or distracted, gently bring your attention back to your breath. You may also find it helpful to silently repeat a mantra, such as "just sitting," to help refocus your mind.

The key to shikantaza meditation is to maintain a state of open awareness, without getting attached to any particular experience or trying to achieve a certain state of mind. It is a practice of simply being present in the moment, without judgment or expectation.

It is recommended to practice shikantaza for at least 20 minutes at a time, but you can start with shorter sessions and gradually increase the length as you become more comfortable with the practice.

In conclusion, shikantaza meditation is a simple yet profound practice of just sitting and being present in the moment. By cultivating open awareness and letting go of attachment, we can experience a sense of peace and clarity in our daily lives. So, find a comfortable place to sit, focus on your breath, and allow yourself to just be.
