Natyashastra
पार्श्वक्रान्तं पुनश्चाद्यं सूचीविद्धे तु मण्डले । आद्यस्तु जनितो भूत्वा स च दण्डक्रमो भवेत् ॥ २१॥
The Pārśvakrānta (sideward movement) should again be the first in the Sūcīviddha Maṇḍala. The initial movement should begin with the Janita (originating movement) and transition into the Daṇḍakrama (staff-like progression).
english translation
