Mastamma (mAstamma) (ಮಾಸ್ತಮ್ಮ) is a simplified version of the world ‘maasti amma’. (mahAsati amma) Maasti belongs to the category of family deities among the female deities of Karnataka. The remaining two are village deity and clan deity. However this Mastamma relinquishes her life in the presence of her husband and not after his death.
According to the oral tradition
Mastamma was born in Hulivaana
Mastamma temple is to be found in Hosakere village even to this day. It contains two enclousures. Inner sanctum contains the statue of Mastamma.
Similar stories are in vogue in some parts of Tumkur district also. The devotees of mastamma go to her temple on auspicious occasions. Special dishes are offered to the deity. Women are forbidden from entering the sanctum sanctorum. They worship the goddess whenever new clothes are worn by them. Those who cannot make it to the temple worship three stones and a pitcher full of water near a river or a tank. Newly wed couples are obliged to perform this worship. The major motifs behind the story and the antecedent details hint at
‘mahAsati’ worship. It looks as though a historical incident has gradually acquired legendary dimensions.
