Deep focused reading in Christianity could be regarded as Meditation.
Meditation is a practice or exercise, where an individual trains one's attention and awareness to get to a clearer and calmer state.[1][2][3][4][5][6] Scholars have found meditation difficult to define. The practices vary both between traditions and within them. Generally meditation tries to get past the "thinking" mind and aims to go into a deeper state of relaxation or awareness.
It is a common practice in many religions including Buddhism, Christianity (sometimes), Taoism, Hinduism (where Yoga is important)
and other religions. Meditation has now become a modern trend, showing many health benefits.[7]
The initial origin of meditation is from the Vedic times of India.
