"Lama Zopa Rinpoche recently offered some new advice about lunar and solar eclipses, which are considered auspicious days for practice and provide opportunities for accumulating increased merit.
In addition to Lama Zopa Rinpoche reminding students that the merit generated on lunar eclipses is multiplied by 700,000 and by 100 million on solar eclipses, Rinpoche taught that the multiplying effect of eclipses occurs whether the eclipse is partial or full. Also, Rinpoche advised that the merit multiplying effect does not last the whole calendar day and that merit making activities should be carried out during the time of the eclipse itself.
Whether or not an eclipse is occurring and its exact timing depends on where a student is on Earth. Websites like timeanddate.com can help students determine if and when there is an opportunity to practice during an eclipse.
Upcoming potential lunar eclipses: July 27, August 26
Upcoming potential solar eclipses: August 11
On these multiplying days, any beneficial practices can be done. In particular, Rinpoche recommends:
Recitation of the names of the Thirty-Five Confession Buddhas
Recitation of Vajrasattva mantras
Any other meritorious activities advised by Lama Zopa Rinpoche are also good to do on these days, such as recitation of the Vajra Cutter Sutra, the Sutra of Golden Light, and the Sanghata Sutra, with extensive dedications. These texts are available on the “Sutras” page on FPMT.org."
