This is Kawaguchi Hidetoshi. This is a humble answer to the question.
I know that having a spirit of “separation” is truly precious and important when entering Buddhism.
In the midst of this reincarnation, by realizing that true comfort can never be obtained, sincerely dislikes this reincarnation, and a strong desire to leave or be liberated at any cost becomes “separation.”
Furthermore, in this reincarnation, it is not just me who is suffering, and by realizing that everyone is suffering uniformly, it also awakens a heart of sorrow (great sorrow) about everyone's suffering, and by awakening a heart of compassion (great kindness) that wants to save and help all sentient beings that are related to various things at any cost, it is desired that “bodhicitta” be discovered next to “escape.”
I believe that it is the first and most important condition for becoming a “monk” that will certainly cause “separation” and “bodhisattva heart.”
Whether at home or in a monk, I know that it is more desirable than anything else to continue to maintain this “separation” and “bodhisattva heart” firmly and devotion to good deeds. Also, if the time comes to maturity, you may be able to officially walk on the path to becoming a monk, and even if you are not blessed with the chance to become a monk and remain at home, I know that the sustenance of good deeds and devotion will surely bring great benefits (riyaku) in the future and future generations as a guide to true Buddhism.
The following quotes are from Tibetan Buddhism, but I would be happy if you would take this opportunity to refer to them and give them further thoughts on “exile” and “bodhicitta.”

From Ramzo Namsum (The Three Keys to the Road)...
“Without a clean separation, we will continue to pursue the fruits of happiness in the bitter sea of reincarnation, and there is no convenient (means) to calm it down. Affectionate people (all living things) are all bound by the anguish of being attached to reincarnation, so they should pursue separation first.”
