Tibetans know that no matter what stupas look like on the outside, they contained incredible blessings. Just to see them was a blessing. To touch them was a blessing. To hear the sound of the wind blowing around them was a blessing. And that was why they built them—for the blessings, just the blessings.
The blessings of stupas are such that they benefit all beings, regardless of their connection or motivation. The state benefits. The local area benefits. There is benefit in all levels. But that benefit is increased by one's participation and one's bodhicitta. A stupa is especially beneficial to those who sponsor or build it, see it or hear the wind that blows by it, touch or remember it, but that does not mean that it is not beneficial to other beings. It is really more a question of the degree of benefit........
One meaning of “stupa” is that it is a self-arising, spontaneously occurring phenomenon. In this sense, the configuration of the entire universe—conceived in traditional Buddhist cosmology as four continents surrounding Mount Meru as the central axis, crowned by the realm of the gods with the wish-fulfilling tree growing in it—can be understood as a gigantic stupa. On an inner level, the structure of the “vajra aggregates” of the subtle body, the way a person's mid-body aggregates and sense faculties—all the elements of the individual's experience of the world—fit together and interact, arises as a stupa as well and corresponds to the configuration of the universe as a macrocosm.
There is also a direct correspondence between the architectural features of a stupa and the way the universe is structured. The base and the steps of the stupa correspond to the six realms of beings in the desire realm. The middle, spherical section—the bumpa, or vase—corresponds to the seventeen levels of the form realm. The spire and the ornaments on top of the stupa correspond to the four stages of the formless realm. The srog shing, or central axis, the pole that runs through the center of the stupa, corresponds to dharmadhatu, the basic space of all phenomena. ......
