Shikantaza, also known as "just sitting" meditation, is a form of meditation practiced in Soto Zen Buddhism. It is a technique that focuses on simply sitting and being present in the moment without any specific goal or object of focus. This form of meditation is different from other forms of meditation in several ways.

Firstly, shikantaza does not involve any specific object of focus, such as the breath or a mantra, as is common in other forms of meditation. Instead, the practitioner is encouraged to simply sit and observe their thoughts, feelings, and sensations without trying to control or change them. This allows for a more open and expansive experience, as there is no particular goal or expectation to achieve.

Secondly, shikantaza does not involve any deliberate effort or concentration. In other forms of meditation, there may be a focus on maintaining a certain posture or repeating a specific mantra. However, in shikantaza, the emphasis is on letting go of any effort or striving and simply being present in the moment. This can be a more relaxed and natural approach to meditation, allowing for a deeper sense of peace and stillness.

Another key difference is that shikantaza does not involve any visualization or guided imagery. In some forms of meditation, there may be a focus on visualizing certain images or scenarios to cultivate certain qualities or states of mind. However, in shikantaza, the focus is on being present with whatever arises in the mind without trying to manipulate or control it. This can lead to a greater sense of acceptance and non-judgment towards one's thoughts and experiences.

Additionally, shikantaza is not focused on achieving a specific outcome or result. Other forms of meditation may have specific goals, such as reducing stress or increasing focus. However, in shikantaza, the emphasis is on simply being present and observing the mind and body as they are. This can lead to a more open and non-judgmental attitude towards one's experiences, which can have a transformative effect on one's overall outlook on life.

In conclusion, shikantaza is a unique form of meditation that differs from other forms in its emphasis on open awareness, non-effort, and non-judgment. Its simplicity and lack of specific goals or techniques can make it a refreshing and liberating practice for those seeking a more natural and open approach to meditation.
