Stotram is a Sanskrit word that means eulogy or hymn of praise and prayer, which is dedicated to a certain deity. Mohani Heitel sings all the stotras of this series in her own musical composition accompanying herself with Tanpura. Most of these stotras were written by the medieval Indian saint Adi Shankara. Singing stotras or listening to them with undistracted attention helps to feel the presence of the corresponding deity, and serves to express devotional feelings. Mohani Heitel has compiled six parts which contain Shiva stotras (Vol. 1 and 2), Devi stotras (Vol.1 and 2), and one each for Vishnu stotras, and one for stotras of Ganesha together with Subrahmanya (Kartikeya). Ganesha is a popular deity - also called i.a. Ganapati, Vinayaka or Vighnesha - brother of Subrahmanya, both the sons of Shiva and Parvati. Ganesha is the remover of obstacles in pursuit of both, material as well as spiritual achievements. He is often invoked and adored at the beginning of prayers, ceremonies, rituals, art performances and other auspicious occasions. Titles 1-7 are dedicated to Ganesha. Subrahmanya is i.a. also called Murugan, Guha, Kumara, Skanda and Kartikeya. As Senapati He is the leader of the army of the Gods to conquer the evil forces. Subrahmanya is widely adored as God of wisdom, valour, justice, and compassion. Titles 8-11 are dedicated to Him. Stotras are devotional and magical texts at the same time, the presence of the deity and its attributes can be easily evoked by their pronunciation. According to the faith of the ancient Indians the word possesses a sensual magic power. The voice as a sensitive body organ is the carrier of the sacred word. The singer brings a certain degree of emotionality with him, due to his personal religious closeness for each text. This empathy degree transmits on the voiceprint of the rendition. Stotra is an eulogy. Revelation plays an important role in setting words of a stotra to music. The music comes in dreams or strikes one in the middle of some activity, and one is consumed by the tune. Stotras as prayer hymns contain elements to help the aspirants by a kind of mental cleaning on the way to the divine presence. The Stotram literature is full of religious symbols, metaphors and allusions to myths. Cult ritual and verbal magic belong together. Stotras have the magical effect of a curative magic text.
