A translation of the Chamakam is posted here. However, no translation can ever capture the mystifying beauty of the Vedic mantras in the original language (proto-Sanskrit). Also, it must be noted that several items being beseeched are those specific to ancient Vedic rituals and do not have names in modern languages. As the Vedic rituals were considered crucial for the well-being of all humanity, praying for the necessary items and correct performance of the ritual plays a central role in the hymn.
When listening to Vedic hymns being chanted, one ought not concentrate too much on understanding the words or the meaning. It is far more important to close one's eyes, mediate, and allow one's mind to be transformed by the divine vibrations therein.
Aum Namah Shivaya, and a blessed Maha Shivaratri to all my readers.
