After Devadatta’s departure, the Buddha taught that the spiritual life is not pursued for acquisitions, respect, popularity, ethical conduct, collectedness, or knowledge and vision. Through the simile of a man seeking heartwood, he cautioned that settling for these lesser accomplishments is like mistaking bark or branches for the heartwood—the true goal being the unshakeable liberation of mind.

When questioned about rival teachers, the Buddha sets the debate aside to explain the true purpose of the spiritual life through the simile of the heartwood. He cautions that settling for fame, ethical conduct, or lesser meditative states is like mistaking branches or bark for the core. The ultimate goal remains the unshakeable liberation of mind.
