Since mindfulness is part of one's stream of consciousness, the practice of meditation cannot be regarded as something alien, as an emulation of some picturesque yogi who has a fixation on meditating all the time. Seen from the point of view of mindfulness of life, meditation is the total experience of any living being who has the instinct to survive. Therefore meditating—developing mindfulness—should not be regarded as a minority-group activity or as some specialized, eccentric pursuit. It is a worldwide approach that relates to all experience: it is tuning in to life.
