Working in his distinctive abstract expressionist style, Basteker fills the composition with vibrant color, expressive gesture, and rhythmic movement. The ascending figures merge naturally with the landscape, suggesting that the journey to Jerusalem is not merely geographical but also deeply personal and spiritual.

Throughout Jewish history, aliya has represented more than immigration to the Land of Israel. The Hebrew word itself means "ascent," expressing the belief that drawing closer to Jerusalem is also an elevation of the soul. Basteker captures this dual meaning through a composition that continually leads the viewer's eye upward toward the city.

Rather than depicting a specific historical event, the painting reflects the timeless experience of generations who dreamed of returning to Jerusalem. Rich in movement, color, and symbolism, Aliya celebrates hope, faith, and the enduring bond between the Jewish people and their eternal capital.
