Arcana Coelestia # 5684
5684. 'And he lifted up his eyes' means reflection. This is clear from the meaning of 'lifting up the eyes' as thought and attention, dealt with in 2789, 2829, 4339, and also observation, 4086, and so reflection; for reflecting is turning one's attention, which is the sight of one's understanding, to observe whether something is true, and having done this to observe that it is indeed so.
Arcana Coelestia # 4339
4339. 'Jacob lifted up his eyes and saw' means the perception and the attention of the good of truth, meant by 'Jacob'. This is clear from the meaning of 'lifting up the eyes and seeing' as perception and attention. For 'lifting up the eyes' is an external action which corresponds to a raising of the mind, an internal activity, and so corresponds to perception, while 'seeing' corresponds to consequent attention. Also, 'Jacob' at this point represents the good of truth, see just above in 4337.
