Bottom lines are addictive behaviours that we make a conscious choice not to repeat. For example, a recovering cocaine addict would create a bottom line that they will not use a mind- or mood-altering substance to deliberately get high. A recovering sex addict might create a bottom line not to watch pornography or not to have sex without any emotional or spiritual connection. Bottom lines are a symbol of our intentions and are very useful at a practical level to address addictions. In many recovery communities, twelve-step fellowships and addiction rehabs, there is also a concept called ‘top lines’.
