Lojong is a practice of training your mind and heart to take on the sorrow and pain of others and, in turn, send them joy and relief.

Long johns are basically long underwear that keeps your legs warm.

Lojong was brought to Tibet in the 11th century by the Indian Buddhist teacher Atisha.

Long johns are also a kind of pastry. They're like rectangular donuts, but with no hole.

Lojong summarizes the essentials of Tibetan Buddhism. These teachings were abridged for ease of memorization and contemplation by Geshe Langri Tangpa in the "Eight Verses for Training the Mind."

Long johns can be folded up and taken with you on camping trips. The silk ones are especially light and portable, yet are more expensive than cotton.

Lojong helps you cultivate a sense of holding dear all sentient beings. It enables you to regard others -- even mean, stupid people -- as precious, like gems.

Long johns come in "circular knit" and "ribbed lightweight" varieties, among others.

Lojong teaches that it is important to develop a genuine insight into emptiness through a rational process of analysis and reflection.

Long johns are sometimes filled with cream and glazed with chocolate.
