KAMASUTRA: The Kama Sutra, Hindu love text, has suggestive names for the different postures and indicates many ways for men to increase their sexual vigor, through foods such as milk and honey, which have always been recognized as a source of drive and energy. This text is the oldest treatise on the art of love or sexual love, which ancient civilizations decided to write down and pass on from generation to generation. In it are compiled the attributes that for the Hindus (creators of the Kama Sutra) were, are and will be as necessary as food and water. These techniques were gathered around 500 A.D. thanks to the scientific-doctrinal Vatsyayana, who gathered the 1000 original chapters and adapted them to western customs. Although the reading at times seems morbid according to the western vision, we must understand that within the Hindu context sex was considered sacred and they did not interpret the words as obscene but simply expressed things by their name; they also argued that a good understanding of the techniques pointed to a better quality of life both physically and spiritually.
