According to Kabbala, from midnight and on is considered a time of Rachamim (divine mercy) even though it is still in middle of the night. Yet from midday and on is considered a time of Din (divine judgement), even though the sun is still high in the sky. Although this seems strange, the reasoning is beautiful. From midday and on, the sun has already began it’s journey to setting; we are already facing towards the night and is therefore a time of Din. On the other hand, from midnight, the sun has began its return journey and we are now facing towards the morning. Therefore it is considered a time of Rachamim – even though it is still the darkness time of the night. From this we can learn a big Yesod. It is the direction that a person is heading that matters to G-d, and notwhere he currently stands.
