The Domestic Sutras of Gobhila

Within ten months to a year, a king who appoints the wrong priest sees his kingdom fall into ruin.
The priest of the Atharvaveda original: "Atharva" can both direct fierce power and pacify terrifying portents.
The Atharvan protects the sacrifice, and the sage Angira is the lord of the sacrifice.
The knower of the Brahmaveda another name for the Atharvaveda is the one who pacifies the various types of ill-omens—whether they be celestial, atmospheric, or terrestrial; therefore, the descendant of Bhrigu the chief priest sits to the south.
The Brahma priest the presiding priest alone can pacify disturbances; neither the Adhvaryu Yajurvedic priest, nor the Chhandoga Samavedic priest, nor the Bahvricha Rigvedic priest are capable of this.
The Brahma priest protects against demonic forces; therefore, the Brahma must be one who is learned in the Atharvaveda. — (Atharva-parishishta)

The assembly of Aryan sages perceived through their divine vision that an unruly human race, if left without rules, would only progress toward a steady decline. They saw that humanity would never set foot upon the auspicious path of the virtuous; rather, driven by their passions, they would constantly perform wicked deeds. Consequently, in such a state, the social fabric cannot remain intact, nor can a sense of religious duty blossom within the human heart. For this reason, with the aim of securing both the worldly and otherworldly benefit of every individual and society as a whole, the great sages systematically established a framework of special rules. Just as the foundation of a house must be made strong before the house itself can be strengthened, the ancient sages warned us even before a human infant is born:

“He for whom the ritual from conception to the crematorium is ordained with sacred hymns original: "mantras", he alone has the right to the scriptures, and never anyone else.” (Manu Smriti: 2:91) This verse emphasizes that spiritual eligibility is earned through the lifelong performance of sacraments.

Therefore, it is the duty of every Aryan to perform all the Samskaras Samskara: life-cycle sacraments or rites of passage intended to refine the individual, beginning with Garbhadhana Garbhadhana: the sacrament of conception, at their proper times. The word Samskara means "purification"—the process of removing flaws and imparting qualities. In other words, through these sacraments, inherent defects in an object are destroyed, and specific virtues are added. Consider a mirror: by its very nature, it is clear and capable of holding a reflection original: "pratibimbagrahita". However, due to a specific defect, it may become covered in grime. As long as that dirt is not removed, its reflectivity and clarity cannot be revealed. For this reason, it requires a "refinement" original: "Samskara". Once that external tarnish is removed through the action of polishing, the "mirror-ness" of the mirror shines forth once again.
