अथ जाते च सायाह्ने भुवि पश्चिमदिण्मुखः । उद्धृत्य दद्यात्प्रातस्तु मध्याह्नेंगुलिभिस्तथा २७ ।
The offering of Arghya in the morning is by lifting both the hands high up; that in the midday by letting off the water through the fingers and that in the evening by letting the water over the ground facing the west.
अंगुलीनां च रंध्रेण लंबं पश्येद्दिवाकरम् । आत्मप्रदक्षिणं कृत्वा शुद्धाचमनमाचरेत् २८ ।
In the midday the sun is to be viewed through the fingers reciting the mantra prescribed for that. The circumambulation of oneself is performed (in the prescribed manner) and the pure Ācamana (without mantras) is performed.
Sandhyā prayer performed before the prescribed time is ineffective. Hence Sandhyā shall be performed at the prescribed time. The expiatory rite for the omission of Sandhyā prayer for a day is the repetition of Gāyatrī a hundred times more than the usual number of times for ten days.
