The depiction of a square is the symbol that finds an identification for itself while destroying it simultaneously. The square is a symbol, a figure that could be seen from the earliest times, where the first religions, that people followed and worshiped, came from. Any ornament that represented one or another belief included a symbol of a square. Houses and temples, that were built, featured a symbol of a square or a cube and thus included deep and eternal meanings in their appearance. Senses could vary from religion to religion, from nationality to nationality, but the symbolism of the square in them has never had negative connotations, even though its meaning in culture was not always clear. 

If we take separately the essence of the square and consider it as a separate symbol, we will see that it either does not make sense at all or has absolute meaning reflected in everything.

A square is also a fixation of death as opposed to a dynamic cycle of life and movement. It combines the principles of static stability and integrity. 

A square represents simplicity, one of those symbols that impoverish and nullify. By placing it in Yantra's Buddhist symbolism, which helps to focus and meditate, the square is further exacerbated in its essence. Realizing the basis of everything, faith, and people, the need for self-identification and identification of the environment disappears. All become one and one.
