Relaxation does everything for everyone, which can be experienced in real-time through noticing how our tactile awareness increases when we chill. If there is a ‘Martial’ force in Jiu-Jitsu it’s this, as a relaxed body is both H-E-A-V-Y and hyper sensitive:

What’s suggested instead is being receptive to the relationship between thought and tension, and having a bit of faith that relaxation will take your Jiu-Jitsu far, far beyond linear, A+B=C processes. This at times means giving up our preconceptions, which are just that, preconceptions!
An insight just had writing this is, this has massive technical applications because the best ‘Jiu-Jitsu’ positions WORK from a relaxation premise in that we’re not trying to control anyone thing, but be loose and responsive enough to manage all things.
Xande Ribeiro teaching a Cross-Side approach that maximizes the effect of relaxation:
To sum things up, relax and use the force in all things from selecting to studying on through applying positions.
