"So when you are alert and contemplate a flower, crystal, or bird without naming it mentally, it becomes a window for you into the formless. There is an inner opening, however slight, into the realm of spirit. This is why these three “enlightened” lifeforms have played such an important part in the evolution of human consciousness since ancient times; why, for example, the jewel in the lotus flower is a central symbol of Buddhism and a white bird, the dove, signifies the Holy Spirit in Christianity. They have been preparing the ground for a more profound shift in planetary consciousness... the spiritual awakening that we are beginning to witness now."
