Involvement
At Sāvatthī. “Mendicants, if you get involved, you’re not free. If you’re not involved, you’re free. Should consciousness involved with form, supported by form, established on form continue to remain, with a sprinkling of relishing it would grow, increase, and mature. Or should consciousness involved with feeling remain … Or should consciousness involved with perception remain … Or should consciousness involved with choices, supported by choices, established on choices continue to remain, with a sprinkling of relishing it would grow, increase, and mature.
