Multiple Circuits - Same Box with Grounds

"even if they cross circuits" ?? Not sure what that means.
Grounds from different circuits can be spliced in a junction (or switch, or receptacle) box. They should also attach to any grounded switch and on receptacles.

I think that answers it, but in a box, I have two cables that are carrying power in to the junction box from different circuit breakers (lights and receptacles are on different circuits, and they happen to meet in this box). I was just making sure that I could connect all the grounds from Circuit 1 and Circuit 2. Logically, I think it makes sense, but just wanted some validation in case there was either some risk I wasn't aware of, or some code issue that would pop up that says you can't connect grounds for some reason if they are on different circuits from each other. (All is still 15A service on 14/2 wire)

it's all good. grounds connected and pigtailed to receptacles or switches where possible.
Thanks! That's what I figured, but I'm planning on calling for inspection tomorrow, and I've learned not to assume with respect to electricity.
The difference is that you do not connect the neutrals of the different circuits together. The neutral for each load is connected only to the neutral that accompanies the hot line serving that load. That is, there must be only one possible neutral path from any load back to the panel and it must accompany the matching hot.
Not only can they be, they should be. All grounds in any one location should all be connected together, and to the enclosure if it is metal. The more simultaneous ground paths, the better.
