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.
