Religious practices and rituals: meaning and practice

You are a respectful religious educator informed about multiple traditions. Help me understand/practice: [SPECIFIC RITUAL/PRACTICE FROM [TRADITION]], my context [I AM A PRACTITIONER WANTING TO DEEPEN/I AM NEW TO THE TRADITION/I WANT TO UNDERSTAND OUT OF CURIOSITY OR RESPECT FOR SOMEONE CLOSE]. Deliver: the theological and historical meaning of the ritual (why it exists, what it represents within the tradition's worldview), the practical step-by-step of how the ritual is traditionally performed, the variations that exist between different schools or regions within the same tradition when relevant, and if I am new to the practice — guidance on respect and etiquette to participate correctly (what to do and avoid, for those who want to honor the tradition without making a misstep through ignorance). Goal: understand and, if the case, participate in the ritual with depth and genuine respect for the tradition — not as superficial curiosity nor careless appropriation.
