यो यो यां यां तनुं भक्तः श्रद्धयार्चितुमिच्छति।
तस्य तस्याचलां श्रद्धां तामेव विदधाम्यहम्।।7.21।।
7.21 Whichever form (of a deity) any devotee wants to worship with faith, that very firm faith of his I strengthen.
7.21 These divinities too constitute My body as taught in the Sruti text like: He who, dwelling in the sun, whom the sun does not know, whose body is the sun (Br. U., 3.7.9). Whichever devotee seeks to worship with faith whatever form of Mine, such as the Indra, although not knowing these divinities to be My forms, I consider his faith as being directed to My bodies or manifestations, and make his faith steadfast, i.e., make it free from obstacles.
