My very dear Kevin,
Thank you very much for your kind letter. If you returned your vows without breaking them, or even if you broke them but you did not hide that, then it’s OK, you can take ordination again. It is especially good to do that now your mind has become stronger. So, it’s OK, you can take them again. Then, you should continue your life in that way, thinking of its purpose, until you achieve stable realizations, bodhicitta, and special insight.
With much love and prayers...
