Samjnana Suktam is a hymn for unity of thought. It is the last hymn of the Rig Veda Samhita (X.191). It consists of four mantras (verses). The deity of the first verse is Agni. Samjnana is the deity of the rest of the verses. The term samjnana means ‘unity in thought.’ Unanimity at the intellectual level among those gathered in an assembly is sought in this hymn. The name of the rishi (the seer) of this hymn is Samvamana, which also indicates the quest for unity. Moreover, these verses are repeated with minute changes in Atharva Veda Samhita (VI.63.4, VI.64), where the deity or subject of these verses is referred to as Samanasya, which gives a similar sense. Samjnana Sukta (or a few verses from it) are found in other Vedic texts, too, and thus its importance in the Vedas is pretty evident.
This hymn illustrates the significance of unanimity or agreement in general assembly of the people for some common cause on certain important occasions. The first verse, addressed to Agni, is not directly related to this concept. It presents the prayer of might Agni for bringing all living beings together. The next three verses of this hymn point out the instructions which, when followed, lead to peace and harmony in a group or society – Meet together, talk together, let your minds apprehend alike in a like manner as the ancient Gods concurring accepted their portion of the sacrifice. Common be the prayer of these (assembled worshipers), common be the acquirement, common associated purpose be the desire, I repeat for you a common prayer, I offer for you with a common oblation. Common be your intention, common be your hearts, common be your thoughts so that there may be thorough union among you.” This is one of the popular Vedic hymns and has its place in special prayers and rituals, too.
