Shikantaza, also known as "just sitting" meditation, is a form of meditation practiced in Soto Zen Buddhism. It is a simple yet profound practice that involves sitting in a relaxed and upright posture, with eyes slightly open and focused on a spot in front of you.

The goal of shikantaza is to simply be present in the moment, without any specific goal or object of focus. This allows the mind to settle and become still, without being distracted by thoughts or external stimuli. It is a practice of non-doing, where one simply allows things to be as they are without trying to change or control them.

In shikantaza, the emphasis is on the act of sitting itself, rather than any particular outcome or experience. This is in contrast to other forms of meditation that may have a specific goal or object of focus, such as counting breaths or repeating mantras.

The practice of shikantaza can be challenging, as it requires a deep level of self-awareness and the ability to let go of any expectations or desires. It is a practice of surrendering to the present moment, and allowing the mind to naturally settle and become still.

Through shikantaza, one can cultivate a sense of inner peace and clarity, as well as a deeper understanding of the nature of the mind. It is also believed to help develop mindfulness and concentration, which can be beneficial in daily life.

In Soto Zen, shikantaza is often practiced in conjunction with zazen, which involves sitting in meditation for extended periods of time. However, it can also be practiced for shorter periods, such as 15-20 minutes, as part of a daily meditation routine.

Overall, shikantaza is a powerful and transformative practice that can help individuals connect with their true nature and experience a sense of oneness with the present moment. It is a key aspect of Soto Zen Buddhism and is often considered the highest form of meditation in this tradition.
