The supreme divine power whom we call as god or Paramaatma resides within our own selves in our heart. This has been categorically emphasized in the Narayana Suktam of the Taitreeya Aranyaka.
पद्मकोश प्रतीकाशं ह्रदयं चाप्यधोमुखम् |
अधो निष्ठ्या वितस्त्यान्ते नाभ्यामुपरि तिष्ठति |
ज्यालमालाकुलं भाति विश्वस्यायतनं महत् |
संततं शिलाभिस्तु लम्बत्याकोश सन्निभम् |
तस्यान्ते सुशिरं सूक्ष्मं तस्मिन् सर्वं प्रतिष्ठितम् |
The heart is symbolized as an inverted lotus bud. The heart is situated at a distance of one finger span below the throat and above the navel. The region of the heart shines as in a flame and it is here that the great abode of the universe exists. The heart surrounded by arteries is suspended as if it is an inverted lotus bud. In the midst of the heart lies a subtle space in which everything is supported.
तस्य मध्ये महान् अग्निः विश्वार्चिः विश्वतोमुखः |
सोग्रभुग्विभजन्तिष्ठन् आहारमजरः कविः |
तिर्यगूर्ध्वम् अधश्शायि रश्मयस्तस्य सन्तता |
संतापयति स्वं देहम् आपादतलमस्तकः |
तस्ये मध्ये वह्निशिखा अणीयोर्ध्वा व्यवस्थितः |
In the middle of that, there is a great omnifaced flame (Agni). This undying intelligent force consumes & distributes. The rays of this Agni spread both horizontally and vertically and provide warmth to the entire body from the sole of our feet to the head. In the midst of this flame is the tip which is both supreme and subtle.
नीलतोः यदमध्यस्थात् विद्युल्लेखेव भास्वरा |
नीवारशूकवत्तन्वी पीता भास्वत्यनूपमा |
तस्या शिखाया मध्ये परमात्मा व्यवस्थितः |
स ब्रह्म स शिवः स हरिः सेन्द्रः सोक्षरः परमः स्वराट् |
It shines like a flash of lightning in the midst of a dark cloud. It is slender as a grain of paddy, shines like gold and extremely subtle. In the tip of that resides Paramaatma. You may think of that supreme permanent ruler as Brahma, Shiva, Hari, Indra.
