To me precepts and lineage are alive in one’s experience, not an outward “signing up for” or “belonging to”. It is a natural process of awakening to your original nature.
The sixteen bodhisattva precepts are a set of vows of ethical conduct taken by a Zen practitioner when he/she is ready to make a commitment to conduct that benefits others, and are taken by both monastic and lay practitioners. I took/take the sixteen Bodhisattva vows as an expression of inner connection and commitment to Buddhadharma. I am not concerned with outwardly belonging to a particular sect or lineage. To me, the precepts are not some sort of credentials that make you officially belonging to a particular Buddhist lineage. Living lineage is present when one realizes one’s true nature or essence of mind, then all the Buddhas and Patriarchs are truly alive in your very being. A person only becomes a ‘lineage holder’ when, following sustained practise, they gradually realize the inner meaning of the transmitted teachings and infuse them with all aspects of their being. It is nothing but a concept and distraction otherwise.
