In preparation for our two-week long May 2024 Chan Meditation Retreat in the USA, we held a puja the day before, a special ceremony where prayers are offered to the Buddhas for the benefit of all sentient beings and world peace. Our past actions shape our world and experiences. Harmful actions bring suffering, while positive ones lead to happiness. By performing a puja, we can purify obstacles caused by past actions and generate merit, which is needed to achieve any goal. Making offerings to Buddhas, bodhisattvas, dharma protectors, various enlightened beings, and the sangha community strengthens this positive potential.
