Shikantaza, also known as "just sitting" meditation, is a form of meditation practiced in Soto Zen Buddhism. It involves sitting in a relaxed and upright posture, with a focus on being present in the moment without any specific goal or object of concentration. This type of meditation can be practiced alone or in a group, but the question arises, is it necessary to have a teacher or guide for shikantaza meditation?

The short answer is no, it is not necessary to have a teacher or guide for shikantaza meditation. In fact, the essence of shikantaza is to let go of any external guidance or direction and simply be present with oneself. However, having a teacher or guide can greatly enhance one's practice and understanding of shikantaza.

A teacher or guide can offer valuable guidance and support in one's meditation practice. They can provide instruction on proper posture, breathing techniques, and ways to deal with distractions and hindrances that may arise during meditation. They can also offer insights and teachings on the principles and philosophy of shikantaza, which can deepen one's understanding and practice.

Furthermore, a teacher or guide can offer personalized guidance and support, tailored to an individual's specific needs and challenges in their meditation practice. They can also offer a sense of accountability and motivation, as one may feel more inclined to continue their practice with the guidance and support of a teacher.

In addition, shikantaza is a part of a larger tradition and lineage of Soto Zen Buddhism. Having a teacher or guide can connect one to this lineage and provide a sense of community and support in their practice. This can also provide opportunities for further learning and growth through retreats, workshops, and other teachings offered by the teacher or guide.

However, it is important to note that a teacher or guide is not essential for the practice of shikantaza. It is ultimately a personal and individual practice, and one can still experience the benefits of shikantaza without a teacher or guide. It is also important to find a teacher or guide that resonates with one's own values and beliefs, as a harmonious relationship between teacher and student is crucial in the practice of shikantaza.

In conclusion, while it is not necessary to have a teacher or guide for shikantaza meditation, having one can greatly enhance and support one's practice. It is ultimately up to the individual to decide whether or not to seek guidance in their shikantaza practice, and to find a teacher or guide that aligns with their own personal journey.
