Step 1: Understanding the Concept:
The question asks for the name of a circular ('Mandalakar') dance form associated with Lord Krishna.
Step 2: Detailed Explanation:
- Raaslila (or Ras Leela) is the traditional dance drama of Vrindavan, which depicts the divine love story of Krishna and the Gopis (milkmaids). Its most iconic representation is the 'Maha Raas', where Krishna multiplies himself to dance with each Gopi in a large circle. This is a quintessential 'Mandalakar' dance.
- Hallisaka is an ancient term from texts like the Natyashastra for a circular group dance led by one man and many women, which fits the description but 'Raaslila' is the specific name of the performance tradition.
- Kathak and Satriya are classical dance forms that are not primarily defined as circular group dances, although they may contain such elements.
Step 3: Final Answer:
Raaslila is the famous 'Mandalakar' dance form that revolves around Lord Krishna.
