The basic principle is to concentrate on work or sports, enter a state of flow, and experience joy through activity and action.

This can be done in everyday life, even without being particularly spiritual or meditating. When you work and concentrate very intensely, you enter a state of flow, becoming one with the work and experiencing a state of joy.

This is a fundamental aspect of meditation, corresponding to the stages of Dhyana (meditation) or Dharana (concentration).

Some people may mistakenly consider this to be Samadhi, but that is not necessarily the case. In terms of stages, it is still the stage of Dharana (concentration). Even at that stage, there is joy, and you are enveloped in immense emotional happiness.

This is a purification from suffering, a healing, and a joy in itself.

This is an emotional joy, and while it is still an entry point in meditation, like athletes who strive to enter a state of flow and perform at their best, it can be quite difficult to enter this state of flow, even at that stage.

This is a focused concentration on an object. By integrating consciousness with the object of concentration, such as work or sports, you enter a state of flow, gain a deeper understanding of the work or sport, and this dramatically improves performance.

In sports, you may win more games, and in work, the quality will improve.

In reality, this is the fundamental principle of spirituality.

This stage can be practiced through meditation in a spiritual context, but it is much easier to practice it through work, by aligning your consciousness with the content of your work. This is because it involves "an object," and concentrating on an object is easier to do in the field of "work" in your daily life.

When you work, you may initially feel confused, but eventually, a feeling of joy will arise, and you will understand the content of your work. At the same time, you will be healed by the joy, and your energy will be filled. This is a joy as an emotion, and it is a relatively temporary joy, but even so, if you are living a life of depression in your daily life, such joy and healing will be very helpful.

Initially, this may only happen once a year, or even less. Eventually, you will be able to enter the state of flow and experience joy once a month. Then, you will be able to enter it once a week, and eventually, you will be able to enter it almost every day.

At that point, it becomes stable, the ups and downs of bliss decrease, and at the same time, joy spreads to everyday life.

At this stage, it is not yet Samadhi, but rather a stage where meditation (dhyana) has spread to everyday life.

However, even if it doesn't reach the level of Samadhi in daily life, meditation (dhyana) itself can enrich everyday life to a considerable extent. Mindfulness, for example, aims for this level, and if the goal is to enrich everyday life, aiming for this level is sufficient.
