Taken from The Night That Unites Passover Haggadah
Rabbi Aaron Goldscheider
Rabbi Abraham Isaac Kook teaches that the 15 steps of the Seder are to be viewed as rungs in a ladder and are intended to to move us toward a spiritual ascent on the night of Passover. He was once asked, “Who is on a greater spiritual level, a person on a low rung or on a high rung of the spiritual ladder?” He answered: “It depends which direction the person is moving. If the person on the low rung is climbing and growing day by day, he/she is spiritually alive and engaged. Conversely, if a person on a high rung is moving downward, he/she has lost spiritual elan and may continue to sink.
