If this works for her, that's amazing. There is no one true way to practice meditation but I always suggest people to start with the simplest way. Techniques come and go, the key is still maintaining the discipline to practice it.

Joining a community of practitioner is also very beneficial - this is how in the Buddhist traditions meditation is taught and discussed - however it's not always possible depending where you are.

Meditation though is not a silver bullet. If it works for you great, if it doesn't benefit you, move on.
