Nepal’s strong ties to Hindu and Buddhist traditions have made it an ideal destination for meditation retreats.
When choosing a meditation retreat to attend in Nepal, it’s a good idea to look into whether they cater to advanced practitioners or those with a casual interest in meditation. While you may hear about meditation retreats at monasteries all over the country, many of these are based on long-term goals (think, three years-plus) for monks in training and aren’t open to beginners.
There are plenty of opportunities to experience meditation sessions in Nepal. You can join a retreat in a monastery or private center and practice the treachings that have enlightened so many or find a peacefull spot. Famous holy places   like
