With an open mind and a contented heart, the six senses are at peace.
步步清凉彼岸。
Every step brings me closer to the coolness of the other shore (the afterlife).
九载能除四相，
In nine years, I can eliminate the four signs of decay (referring to the traditional belief in the four signs of aging: white hair, wrinkled skin, weakened teeth, and impaired vision).
十年决到三山。
In ten years, I will reach the Three Mountains (a metaphor for longevity and immortality).
