In religions such as Buddhism and Hinduism, meditation involves breathing techniques, posture, and chanting certain repetitive sounds (a mantra) to empty the mind and achieve a feeling of tranquility and connectedness with an impersonal divine being. Roman Catholicism has promoted meditation especially in the form of imagining the physical sufferings of Christ in a way that stirs sympathetic emotions, or repeating set prayers to Mary and the saints. The Puritan practice of meditation is quite different from any of these.
Puritan meditation engages the mind with God’s revealed truth in order to inflame the heart with affections towards God and transform the life unto obedience. Thomas Hooker defined it like this: “Meditation is a serious intention of the mind whereby we come to search out the truth, and settle it effectually upon the heart.” The direction of our minds reveals the truest love of our hearts, and so, Hooker said, he who loves God’s Word meditates on it regularly (Psalms 119:97). Therefore, Puritan meditation is not repeating a sound, emptying the mind, or imagining physical sights and sensations, but a focused exercise of thought and faith upon the Word of God. – Joel Beeke.
