The Das Mahavidya Kavach is the most powerful Kavach for wish fulfillment, spiritual upliftment and knowledge. In Tantra, worship of Devi-Shakti is referred to as a Vidya. The Divine Mother is worshipped as ten cosmic personalities, the Das Mahavidya. Here das means ten and "mahavidya", comes from the root of sanskrit words Maha and vidya in which maha means great and vidya means education that results in understanding and the spread of knowledge, enlightening or astonishing disclosure, nirvana. Successful sadhana of these Vidyas gives several boons to the practitioner. The Tantrik-Yogi who has control over his senses and positively inclined uses the boons to guide people and for the benefit of mankind. The Mahavidyas are considered Tantric in nature .
