Then circumambulate, repeating the Sûrya Mantra. The one thing to be noted in offering Arghyas is this:-- Offer once in the midday, and three times in the morning and three times in the evening. While offering the Arghya in the morning, bend yourself a little low; in offering the arghya in the midday, stand up; and while offering the arghya in the evening, it can be done while sitting. Now I will tell you why the Arghya is offered to the Sun. Hear. Thirty Koti Râksasas known as the Mandehas, always roam on the path of the Sun (the mental Sun also). They are great heroes, treacherous and ferocious. They always try to devour the Sun, while they assume terrible forms. For this reason the Devas and the Risis combined offer the water with their folded hands to the Sun, while they perform the great Sandhyâ Upâsanâ. The water thus offered, becomes transformed into the thunderbolt and burns the heads of the cruel demons (and throws them on the island Mandehâruna) Therefore the Brâhmanas daily do their Sandhyopâsana. Infinite merits accrue from this Sandhyâ Upâsanâ. O Nârada! Now I am speaking to you of the Mantras pertaining to the Arghya. No sooner they are pronounced the full effects of performing the Sandhyâs are obtained. I am That Sun; I am That Light; I am That Âtman (Self); I am S’iva; I am the Light of Âtman; I am clear and transparently white; I am of the nature of all energy; and I am of the nature of Râsa (the sweetness, all the sweet sentiments). O Devî! O Gâyatrî!

O Thou! Who art of the nature of Brahmâ! Let Thee come and preside in my heart to grant me success in this Japa Karma. O Devî! O Gâyatrî! Entering into my heart, go out again with this water. But Thou wouldst have to come again. Sit thus on a pure seat and with a single intent repeat the Gâyatrî, the Mother of the Vedas. O Muni! In this Sandhyopâsanâ, the Khhecharî Mudrâ ought to be done after practising the Prânâyâma. Hear now the meaning of the Khhechâri Mudrâ. When the soul of a being leaves the objects of senses, it roams in the Âkâs’a, i.e., it becomes aimless when the tongue also goes to the Âkâs’a and roams there; and then the sight is fixed between the eyebrows; this is called the Khhechâri Mudrâ. There is no Âsana (seat) equal to Siddhâsana and there is no Vâyu (air) equal to the Khumbaka Vâya (suspension of air in the body). O Nârada! There is no Mudrâ equal to the Khhechâri Mudrâ. One is to pronounce Pranava in Pluta (protracted) accents like the sound of a bell and, suspending his breath, sit quiet motionless in Sthirâsana without any Ahamkâra (egoism). O Nârada! I am now talking of Siddhâsana and its characteristic qualities. Hear. Keep one heel below the root of the genital and the other heel below the scrotum; keep the whole body and breast straight and motionless; withdraw the senses from their objects and look at the point, the pituitary body, between the eyebrows. This posture is called the Siddhâsan and is pleasant to the yogis.

After taking this seat, invoke the Gâyatrî. “O Mother of the Vedas! O Gâyatrî! Thou art the Devî granting boons to the Bhaktas. Thou art of the nature of Brahmâ. Be gracious unto Me. O Devî! Whoever worships Thee in the day gets his day sins destroyed and in the night, night sins destroyed. O Thou! Who art all the letters of the alphabet! O Devî! O Sandhye! O Thou who art of the nature of Vidyâ! O Sarasvatî! O Ajaye! O Thou immortal! Free from disease and decay. O Mother! Who art all the Devas! I bow down to Thee.” Invoke the Devî again by the mantra “Ojosi, etc,” and then pray:-- “O Mother! Let my japam and other acts in Thy worship be fulfilled with success by Thy Grace.” Next for the freedom of the curse of Gâyatrî, do the things properly. Brahmâ gave a curse to Gâyatrî; Vis’vâmitra gave a curse to Her and Vas’istha also cursed Her. These are the three curses; they are removed in due order by recollecting Brahmâ, Vis’vâmitra and Vas’istha. Before doing Nyâsa, one ought to collect oneself and remember the Highest Self; think in the lotus of the heart that Purusa (Person) who is Truth; who is all this Universe, who is the Highest Self and who is All knowledge and who cannot be comprehended by words. Now I am speaking of the Amganyâsa of Sandhyâ; Hear. First utter Om and then utter the mantra. Touch the two legs, saying “Om Bhuhpâdâbhyâm namah” Touch the knees, saying “Om Bhuva Jânubhyâm namah” Touch the hip, saying “Om Svah Katibhyâm namah”

Touch the navel, saying “Om Maharnâbhyai namah” Touch the heart, saying “Om Janah Hridayâya namah” Touch the throat, saying “Om Tapah Kanthâya namah” Touch the forehead, saying “Om Satyam Lalâtâya namah” Thus perform the Vyârhiti nyâsa. Next perform the Karâmganyâsa thus:-- Om Tat savituh ramgusthâbhyâm namah (referring to the thumb); Om Varenyam Tarjanîbhyâm namah (referring to the forefinger); Om bhargo devasya madhyamâ bhyâm namah (referring to the middle finger); Om Dhîmahi anâmikâbhyâm namah (referring to the ringfinger); Om dhîyo yonah, Kanisthâbyâm namah (referring to the little finger); Om prachodayât kara tal pristhâbhyâm namah (referring to the upper part and lower part of the palm and all over the body).
