Chasidut sobre Isaías 29:13

There are some who pray in melancholy, from an excess of black bile, and think that they are praying with great awe. So too, there are some who think that they are praying out of great love for the Creator, on account of their blood, the red humour. When, however, one is in a state of loving God, and as a result shame falls upon them, and they want to glorify the Blessed One and defeat the evil urge on God's account - this is very good. One is not considered a worshipper of God without the qualities of awe and love. One should allow awe to fall on them, and not arouse themselves to awe, which would be drawing up the mayim nukvin, the feminine waters. Real awe is when fear and terror fall upon you, and out of fear you have no idea where you are, and the mind clears and tears fall on their own. When it is not like this, even though it may seem that one loves the Creator, it is surely not so for "This is the gate to God" (Psalms 118:20): awe is the gate that leads to love, and if one does not go through the gate of awe, how can one be in a state of love? Such a person is not even a servant, much less a person on the level of having awe fall on them - they are not worshipping in a way that befits a Jew at all, only serving God out of automatic reflexes (Isaiah 29:13) and fooling themselves that they are actually serving God and worshipping God with joy. This is nothing but flippant joy, and one should return to God with their entire heart and soul.
