ब्रह्मबुद्ध्या तदैक्यं च सोहं भावनया जपेत् । तानेव ब्रह्मरंध्रादौ कायाद्बाह्ये च भावयेत् ४१ ।
He shall meditate on Vidyeśa, Brahmā, Viṣṇu, Īśa, Jīvātman and Parameśvara stationed in the twelve esoteric centre of the body from Mūlādhāra (basic support) to the Brahmarandhra (the mystical aperture at the crown of the head), as identical with Brahman with the conception of Soham (I am He) and continue the Japa. He shall then meditate on them as stationed outside the body as well.
Starting from the Mahat-tattva (the great principle), one should meditate on the body, which is like a thousand-petaled lotus. Gradually, step by step, one should focus on each part of the body, progressing slowly.
मंत्राणां जप एवं हि जपमादिक्रमाद्विदुः । सहस्रं ब्राह्मदं विद्याच्छतमैंद्र प्रदं विदुः ४४ ।
This is the tradition regarding the Japas. Repetition for a thousand times accords Brahmahood and that for a hundred times accords the region of Indra.
Repetition for less number of times may guard the soul to a certain extent and bring about rebirth in the family of a brahmin. After the worship of the sun, the brahmin shall practise thus every day.
