מוסר אויף תהילים 8:10

It is also beneficial for a man to gaze at the Heavens in order to behold the works of Hashem, may He be blessed. It written in the holy Zohar (Introduction 1b): Rabbi Elazar the son of Rabbi Shimon bar Yochai said, One day I was by the shore of the sea when Eliyahu came and said to me, “Rabbi, do you know the meaning of what is written, ‘Raise your eyes on high and see who created these’ (Yeshayahu 40:26)?” I said to him, “These are the Heavens and their hosts, the works of the Holy One Blessed is He. For it is incumbent upon human beings to gaze upon them and bless Him, as it is written, ‘When I see Your Heavens, the work of Your fingers, the moon and the stars that You estab- lished’ (Tehillim 8:4). Following which it is written, ‘Hashem, our Master, how mighty is Your name in all the earth’ (ibid. 8:10).”
