After establishing metta with an "easy being" we can train the heart to offer goodwill to a person we do not know, and also to one who is challenging for us. Our hearts grow stronger as metta deepens and expands.
We can’t truly open to the waves of life unless we recognize our Oceanness, the formless awareness that is our source. This meditation begins with awakening the senses and then invites us to discover the spacious presence in the background of all experience.
