Shikantaza, or "just sitting" meditation, is a form of meditation practiced in Soto Zen Buddhism. It is a technique that emphasizes non-dual awareness and the cultivation of a clear and calm mind. One question that often arises is whether shikantaza can be done with the eyes closed or open.

The short answer is that shikantaza can be practiced with either the eyes closed or open. However, there are some differences in the experience and benefits of each approach.

When practicing with the eyes closed, the focus is on turning inward and becoming aware of one's thoughts, emotions, and bodily sensations. This can be helpful for those who are easily distracted by external stimuli. With the eyes closed, there is less visual input to draw the practitioner's attention away from their inner experience.

On the other hand, practicing with the eyes open can provide a more inclusive and expansive experience. By keeping the eyes open, the practitioner is able to take in the surrounding environment and become more aware of their surroundings. This can help to cultivate a sense of interconnectedness and oneness with the world around them.

Additionally, keeping the eyes open can also help to prevent drowsiness and maintain a sense of alertness during the meditation. With the eyes open, there is a sense of being present in the moment and not getting lost in one's thoughts.

Ultimately, the choice of whether to practice shikantaza with the eyes closed or open is a personal one. Some practitioners may prefer one over the other, while others may alternate between the two depending on their mood or intention for the meditation.

It is important to note that the focus in shikantaza is not on the eyes themselves, but on the mind and its ability to remain present and aware. Whether the eyes are open or closed, the key is to maintain a relaxed and upright posture, with a clear and focused mind.

In conclusion, shikantaza meditation can be practiced with the eyes closed or open, and both approaches have their own unique benefits. It is up to the individual practitioner to experiment and find what works best for them in their own meditation practice.
