Without owing something to one another, there is no way to meet.

Sakyamuni’s words:
It takes a moment to reach out.
Holding hands take years.
No matter who you meet,
They are the one who is supposed to be in your life.
It is no accident.

Buddha said:
Life is also a journey with pleasure.
The body is the inn where the soul lives,
For boundless, infinite time,
This life is just a passing visit.

Deep and deep destiny,
To walk the same way again and again,
To go to the same place again and again,
See the same person again and again.

Always believe,
There is a meeting in this world,
Not on the road, but in the heart;
There is a feeling,
It is not about being together day and night,
But being a silent companion.

Buddha says:
Looking back 500 times,
Fate only grants us a passing glance.
It is fate to meet each other in this life.
Why bother to hate and to have ill feelings?

Together or separate is destiny.
It is the will of heaven,
We should cherish it.

The following online article goes well with the above teachings, so I included it here as well.

01. No matter who you meet, they are the one who should appear in your life.

This means that no one accidentally enters our lives. Everyone who is around us and interacts with us represents something. Maybe it teaches us something. Maybe it helps us improve a situation. Maybe it offers us a turning point.

02. No matter what happens, this is the only thing that will happen.

What we have experienced is impossible to recreate, and it can never happen in other ways, even the least important details. It is not worth it to say, “If I did something different, it would have turned out different.” No matter what happens, this is the only thing that will happen, and it must happen this way so that we can learn from the experience and move on. In life, every situation we experience is perfect, even if we do not understand why.

03. No matter when things start, it’s the right time.

Everything starts at the right time, not early or late. When we are ready to experience the new moments of life, it is there, ready to begin.

04. It is over, and it is over.

It’s so simple. When something ends in life, it helps us grow. To enjoy what has happened thoroughly, it is best to let go and keep moving forward.
