The Indian scholar Vatsyayana gathered and edited the manuscripts now known as the Kama Sutra sometime during the fourth century around 350 C.E., approximately 1,600 years ago. This is the most famous love manual of all time, offering timeless advice to lovers on how to make a relationship successful. The first English language translation was done by the famous British explorer Richard Burton in 1883. The parts of the Kama Sutra that have retained the most interest of modern readers are the chapters giving explicit instructions for sexual techniques including kissing, scratching, slapping, biting, and sexual intercourse. These sections comprise only approximately 5% of the total content in the Kama Sutra.
