It’s only meditation when there are two minds: Knowing-noting mind and observing mind. If there is only one mind, ‘I’ is always there. The object is not the dhamma, The dhamma is the mind That is being aware.
He turns his mind away from those phenomena, and having done so, inclines his mind to the property of deathlessness: 'This is peace, this is exquisite — the resolution of all fabrications; the relinquishment of all acquisitions; the ending of craving; dispassion; cessation; Unbinding.' (Jhana Sutta - Thanissaro Bhikkhu translation)
In terms of practicing, Sharon Salzberg's Loving-kindness is very accessible. She lays out the instructions pretty simply and clearly. I liked Alan Wallace's The Four Immeasurables for a further discussion of them.
