Amba gave up food and sleep, and practised asceticism standing still for six months in the Yamuna river valley, surviving only on air. She became emaciated and developed matted locks. After that, she stood in the waters of the Yamuna, without food and practised austerities. After that, she spent time standing on her tip toes, having eaten only one fallen leaf of a tree. Her penance for twelve years started burning the heavens and the earth. She then went to Vatsa kingdom, in which many renowned sages lived. She roamed the kingdom, bathing in the sacred waters of the Ganges (Ganga) and the Yamuna. Then, she visited the ashrams of many sages like Narada, Uluka, Chyavana, Vishwamitra, Mandavya, Dwilipa, Ramhrada and Garga as well as sacred sites like Prayag, Bhogavati and holy groves. During her journey, she observed difficult vows and performed ablutions in the holy waters.
