I've been taking a secular mindfulness meditation course, and it has been incredibly helpful so far, if frustrating. I'm still quite new at it, so I drift off probably every two breaths or so, but I'll keep working at it.
It's been harder at home, so I purchased a guided meditation cd and book (Quiet Mind) which has various meditation traditions on it. If I'm having a difficult time on my own, I'll play one or more of them.
I meditate in what my husband and I affectionately call "the library" though it's actually the extra bedroom with a bookcase in it. I put up a little gate across the door which prevents my dog from coming in, but through which our two cats can come and go.
When I meditate with a particular track playing (Sharon Salzberg's Metta meditation), it never fails that my tubby cat climbs up on my lap in the middle of meditation, curls up there, and fills the room with purring like he's a motorboat. I can't help but break into a broad smile, blowing my concentration right out the window, while filling my heart with love.
Cat meditation. It might not be a prescribed type of meditation, but I highly recommend it.
"Monks, a statement endowed with five factors is well-spoken, not ill-spoken. It is blameless & unfaulted by knowledgeable people. Which five?
"It is spoken at the right time. It is spoken in truth. It is spoken affectionately. It is spoken beneficially. It is spoken with a mind of good-will."
