At the deepest level, an 'open heart' is spacious presence, in which the sense of separateness between yourself and the 'other' dissolves and there is the recognition of oneness, of shared consciousness. That recognition is love. Sensing the formless essence in another and recognizing it as one with your own essence - that's what love is. All this is an intrinsic part of the awakened consciousness and the revelation of the spiritual dimension of life.
Eckhart TolleA practice can be helpful, but didn't the Buddha compare it to a raft, suggesting it be abandoned when you reach the other shore?
Eckhart TollePeople can't live with themselves much longer. The planet cannot live with humans much longer! We have the weaponry, destruction of the planet, pollution, destruction of forests, countless manifestations of humans using their intelligence in the service of the dysfunction, the madness. It's a strange juxtaposition. Humans are intelligent, but if you look at history or even watch TV, they're also incredibly stupid.
Eckhart TolleMany people see themselves as a problem that needs to be solved. They also habitually see the present moment as an obstacle that they need to overcome or get away from. With awareness, an inner sense of spaciousness arises that enables you to look at your own mind, which is to say the human mind, with a certain degree of detachment.
