What does the text say about the purpose and process of using an idol in worship?

According to the description of 'Archan' devotion in Chapter 1, the use of an idol is a profound spiritual practice. The process begins when the worshipper invites the 'pure, enlightened, and natural spark of consciousness' from their own heart and places it into the idol. Only then does the worship begin, which may include various offerings and rituals. After the worship and ritual farewell are concluded, the text specifies that this same spark of consciousness should be re-established in its original place within the devotee's own heart, signifying the internal and personal nature of the divine.
