Three points:
1. you can only have one meditative spell in effect at once, and can only cast them when prepping spells. (You have to ready it the day before, and then cast it the next day while prepping.)
2. Visualisation of the mind gives a bonus on skill checks, Visualization of the Mind gives you a bonus on ability checks and skill checks. (Which means body doesn't give +5 init, which is....probably reasonable, from a 2nd level spell)
3. Spontaneous casters cannot benefit from meditative spells.
