The Brazilian supermodel is currently on vacation in Costa Rica with fellow model Kiara Kabukuru and the two have embarked on the challenge to find their inner Zen, reports

Posting a photo of her and Kirara posing with their hands together in prayer via her Instagram account, Gisele wrote on Twitter: "Here we go... 3 days in silence. #goinginward (sic)."

Bundchen, 34, and Kabukuru, 39, seem to be trying to rejuvenate themselves on the break as at the weekend. The former re-posted a image of a basket of vegetables that her personal raw food chef Joanne Gerrard Young had tweeted stating the two beauties were "starting" their "juice cleanse".
