Can you describe the path of 'Archan' devotion and its essential components as mentioned in the source?

The path of 'Archan' devotion is defined in Chapter 1 as expressing love through worship and rituals. The components are both physical and spiritual. The physical acts are performed for the pleasure of the Guru and include tending a garden, cleaning the courtyard, performing bath and prayers, grinding sandalwood, giving a five-nectar bath, and offering food (Naivedya) and Arati. However, the text highlights that the most essential component is that these actions are 'done with love.' The spiritual component involves a profound internal process: the devotee is instructed to invite the 'spark of consciousness' from their own heart into the idol for worship, and after the ceremony, that consciousness should be re-established in its original place within the devotee's heart.
