“Maheswari’s themes are protection, overcoming and prayer. Her symbols are masks, drums and prayer wheels. An epic mother-Goddess figure in the Hindu pantheon and a protective aspect of Lakshmi, Maheswari hears our prayers for assistance in risky, threatening, or seemingly impossible situations. When your back’s to the wall, Maheswari opens a doorway for a clever, smooth exit.
Consider following the Indian custom of dancing to drums while masked and enacting a pantomime in which you victoriously overcome some negativity in your life. If you’re trying to quit smoking, for example, dance over your cigarettes and destroy them. To overcome a broken heart, jump over a paper heart, then carry it with you to manifest Mahesvari’s life-affirming energy in your heart.
A fun version of the Buddhist prayer wheel can be fashioned from a children’s pinwheel. Write your prayers to Maheswari on the blades of the wheel. Then focus on your intent and blow! The movement releases your prayers so Maheswari can begin answering them.
Finally, find something that can act as a drum in this spell for protection and victory. Sprinkle the head of your makeshift drum lightly with rosemary and powdered cinnamon. Then tap it, saying:
‘Away, away, Maheswari, take the problems away.’
Continue until the herbs have been cleared off completely, symbolically clearing away that obstacle.”
(Patricia Telesco, “365 Goddess: a daily guide to the magic and inspiration of the goddess”.)
“Goddess Maheshwari is one among the seven mother Goddesses or Sapta Matrikas. Matrikas (Sanskrit: lit. ‘The Mothers’), also called Matara and Matris, are a group of Hindu Goddesses who are always depicted together. Since they are usually depicted as a heptad, (Sanskrit: ‘Seven Mothers’): Brahmani, Vaishnavi, Maheshvari, Indrani, Kaumari, Varahi, and Chamunda or Narasimhi. However, they may sometimes be eight (Ashtamatrikas: ‘Eight Mothers’). Whereas in South India, Saptamatrika is prevalent, the Ashtamtrika are venerated in Nepal.” 
“In the scheme of the Khadgamala, each of these Eight Mothers represent a human passion that must be overcome and controlled before we can enter further into Sri Chakra. We worship each passion as an aspect of Devi, then internalize it; and when we internalize each deity, we *become* Her, so that She is not separate from us. In that way, we “conquer” each passion, just as – in the first enclosure wall – we conquered each siddhi.
MAheshwari here represents Her subtle aspect as ANGER.” 
“The Matrikas assume paramount significances in the Goddess-oriented sect of Hinduism, Tantraism. In Shaktism, they are ‘described as assisting the great Shakta Devi (Goddess) in Her fight with demons.’ Some scholars consider them Shaiva Goddesses. They are also connected with the worship of the warrior god Skanda.
In most early references, the Matrikas are described as having inauspicious qualities and often described as dangerous. They come to play a protective role in later mythology, although some of their inauspicious and wild characteristics still persist in these accounts. Thus, they represent the prodigiously fecund aspect of nature as well as its destructive force aspect.” 
The Goddess Maheshwari is the power of the god Shiva, also known as Maheshvara. Maheshvari is also known by the names Raudri, Rudrani and Maheshi, derived from Shiva’s names Rudra and Mahesh. The vehicle or Vahana of Goddess Maheswari is Nandi (the bull). Goddess Maheswari is usually depicted as having four arms – two arms are in Varada Mudra (granting wishes) and one is in Abhaya Mudra (protection) and two arms are depicted as holding the Sula (lance) and a Akshamala or a Damaru. The white complexioned, Trinetra (three eyed) Goddess holds similar weapons to Shiva and has numerous other symbols and characteristics of Shiva: when She is depicted with six arms, She carries a Trishula (trident), Damaru (drum), Akshamala (a garland of beads), Panapatra (drinking vessel) or axe or an antelope or a kapala (skull bowl) or a serpent and is adorned with serpent bracelets; and two hands are in the Varada Mudra and the Abhaya Mudra. Sometimes She is shown wearing a crescent moon and the jaṭā mukuṭa (a headress formed of piled, matted hair). In some very rare images, Goddess Maheshwari is depicted as having five face.
