स्वभावरचिते भूमौ समस्थाने च यो भवेत् । समः पादः स विज्ञेयः स्वभावाभिनयाश्रयः ॥ २६९॥
The foot that is naturally placed evenly on the ground and stands in a balanced position is known as Sama (natural) foot, which forms the basis of natural expression.
स्थिरस्वभावाभिनये नानाकरणसंश्रये । चलितश्च पुनः कार्यो विधिज्ञैः पादरेचिते ॥ २७०॥
In steady natural expression, various movements are avoided, but in natural foot placement, movement is again to be performed as prescribed by the experts.
