They are individual session. You don't always need to listen to both. Choose the session that addresses the challenge, the booklet is a guide. Sometimes you listen only to session B and you're done. Or session A and and you're done.

The two sessions Paraliminals are two ways of tackling that challenge and yes sometimes the 1 then 2 or 2 then 1 approach is ideal. It's really the same as using two Paraliminals to help with one challenge. Like Sales Leap before a salary review and Self-Esteem Supercharger or Personal Genius before that for that same salary review meeting. The Paraliminal with two sessions have two ways of coming to the challenge with one title.
