Dasha periods, also known as dasha kalas or dasha mahavidyas, refer to the ten-day periods in the Hindu lunar calendar that are dedicated to the worship of the ten Mahavidyas, a group of ten goddesses in Hindu tantra. The term Dasha translates to "ten" in Sanskrit, and these periods are observed to honor the divine feminine energy. In Hebrew, this concept does not have a direct translation, but it can be loosely referred to as תקופות דאשה (Tekufot Dasha). In Bengali, it is known as দশা কাল (Dasha Kal), and in Tamil, it is referred to as தச காலங்கள் (Tha Sa Kaalam). Each Mahavidya represents a different aspect of the divine mother and is worshipped during her respective dasha to seek blessings, protection, and spiritual growth. These periods are particularly significant in Shakta traditions and are observed with various rituals, prayers, and fasting. The ten Mahavidyas include Kali, Tara, Tripurasundari, Bhuvaneshvari, Bhairavi, Chhinnamasta, Dhumavati, Bagalamukhi, Matangi, and Kamala, each embodying unique qualities and powers.
