The patrician-looking (and rather taciturn) sadhu in the top photograph did tell me that he had a family, had held a managerial position in the Indian Railway from which he earned a pension (now paid to his wife), but had decided to detach himself from temporal life and was currently studying the Vedas. These are the oldest scriptures of Hinduism. He was the embodiment of a real sadhu who had really espoused the Vairāgya, and was far different from the "sadhus" I encountered on the ghats of Varanasi (below) almost 8 years later.
For the Aztec and Toltec pre-Hispanic cultures, death was a natural phase of life. The dead were still members of the community, kept alive in memory and spirit, and during Día de los Muertos, they temporarily returned to Earth. Nowadays, people flock to cemeteries to be with the souls of the dead, and build private altars with photographs of the dead, and their favorite foods and beverages. The gatherings are often joyous in tone, and the families remember the lives of the departed.
