The Zohar refers to the Gates of Mercy that open and close depending on the time of the year, but there is one gate that can always be opened—the Gate of Tears.
When we cry out to God and ask for His help to be more spiritual and sharing, to rid us of those things that keep us locked into ourselves, the Gate of Tears swings wide open. A single minuscule tear is potentially the drop of Light needed to take us through this gate and up to our next spiritual level, allowing us to climb up to a place where we can see that we are constantly surrounded by opportunities to grow and improve ourselves.
Tears rooted in selfishness, tears we cry to get more for ourselves alone, won’t unlock this gate. Only when we cry out to God with the desire to become more than we are today, does the Gate of Tears open, welcoming our requests.
