Sister Teresita Barajuen is believed to be the world record holder for the longest cloistered in a monastery. After 86 years of monastery life, the cloistered nun passed away overnight Wednesday in Spain, at the age of 105.

The cloistered nun joined the monastery life 86 years ago when she was just 19 years old. Sister Maria Romero, who announced her death the following morning, testified that she was similar with many young women who didn't know what they wanted to do. The longest cloistered nun eventually decided to give up her dreams of marrying a prince, and settled down her life as a nun for 86 years.

86 years ago, coincidentally, is also the same time Emeritus Pope Benedict XVI came into the world. The cloistered nun began her spiritual life dedication at the same day Emeritus Pope Benedict XVI was born: April 16, 1927.

Sister Teresita Barajuen agreed with Bill Gates that her 86 years was spent due to her passion as a cloistered nun. She quotes him saying, "You feel happiness when you follow your vocation."

The "longest-serving cloistered nun had initially yielded due to family pressure but found her passion during these 86 years.

She met with Pope Benedict XVI in 2011. Receiving a white rosary from the Pope, she in return gave him a copy of a book that included a testimony of her life, "What's a Girl Like You Doing in a Place Like This?"

"Even if I had married a prince, I would not be happier than I am now," the 86-years cloistered nun told the Global Catholic Network in January this year.
