Yangdon said that TAB celebrates various Tibetan events throughout the year, including the birth of the Buddha.

These events are designed "to improve and encourage and to let more people know about Tibetan culture and tradition," she said.

TAB also sponsors political activities, although Yangdon said she possesses very little knowledge about them.

"I'm interested in Tibetan-China politics, because it involves our life and our home," she said. "[Even] if not actively, I have it at heart."

However, Yangdon said that Lopsang is a political activist who has felt duty-bound toward the Tibetan people and Tibetan exiles since the age of 14.

"I would also like to help the Tibetan government in exile," she added.

For now, Yangdon is more involved in the organization's cultural activities.

She said that it was important for Tibetan expatriates to preserve their heritage and spoke of a Sunday school in Cambridge where "younger ones...are becoming more conscious of our culture" through learning Tibetan language, dances and songs.

Eventually Kesang and Lopsang hope to return to Tibet.

"We want to go to Tibet sometime soon, but it's difficult to enter," she said.

"It's our home," she added, plaintively.
