At the center of the hexagonal in the Gaudiya Matha logo, Sarasvati Thakura placed the bija-mantra Om [in place of klim] along with nama. In the six points [sat] of the Sat-kona he placed the six opulences, i.e. fame [yasa], beauty [sri], knowledge [jnana], renunciation [vairagya], wealth [aisvarya] and strength [virya].
In line with the purports of Bhaktivinoda Thakura in Brahma-samhita, Bhaktisiddhanta inserted Om in place of Klim to show that Klim and Om are non-different. Sahajiyas, and others of his time were of the habit of neglecting mantras such as Om and Brahma-gayatri, whereas Bhaktisiddhanta was of the practice to show how everything in its deeper meaning is related to Krsna. Bhaktivinoda's purport states as follows:
“The Gopala-tapaniya Upanisad states, tasmad omkara-sambhuto gopalo visvasambhavah, klim omkarasya caikatvam pathyate brahma-vadibhih. Omkara means Gopala, who is both Potency and the potent, and Klim means Omkara. Therefore, Klim or the primary desire seed [kama-bija] expresses the transcendental reality of Sri Sri Radha and Krsna.” [Sri Brahma-samhita, purport, Verse 4]
Furthermore, Sarasvati Thakura used the Sat-kona yantra as the floor plan for the temple of Sri Sri Guru-Gauranga-Gandharvika-Giridhari at Sri Caitanya Matha in Mayapura.
