_Devotion_.—As devotion is, in some degree, related to affection, though mainly consisting of reverence, often combined with fear, the expression of this state of mind may here be briefly noticed. With some sects, both past and present, religion and love have been strangely combined; and it has even been maintained, lamentable as the fact may be, that the holy kiss of love differs but little from that which a man bestows on a woman, or a woman on a man.[825] Devotion is chiefly expressed by the face being directed towards the heavens, with the eyeballs upturned. Sir C. Bell remarks that, at the approach of sleep, or of a fainting-fit, or of death, the pupils are drawn upwards and inwards; and he believes that “when we are wrapt in devotional feelings, and outward impressions are unheeded, the eyes are raised by an action neither taught nor acquired.” and that this is due to the same cause as in the above cases.[826] That the eyes are upturned during sleep is, as I hear from Professor Donders, certain. With babies, whilst sucking their mother’s breast, this movement of the eyeballs often gives to them an absurd appearance of ecstatic delight; and here it may be clearly perceived that a struggle is going on against the position naturally assumed during sleep. But Sir C. Bell’s explanation of the fact, which rests on the assumption that certain muscles are more under the control of the will than others is, as I hear from Professor Donders, incorrect. As the eyes are often turned up in prayer, without the mind being so much absorbed in thought as to approach to the unconsciousness of sleep, the movement is probably a conventional one—the result of the common belief that Heaven, the source of Divine power to which we pray, is seated above us.
