हृदयस्य शतं च एका च नाड्यः सन्ति । तासाम् एका मूर्धानाम् अपि निसृता। तया उर्ध्वम् आयन् अमृतत्वम् एति। अन्याः विष्वक् उत्क्रमणे भवन्ति ॥
कठोपनिषद् 2.3.16
hr̥dayasya śataṁ ca ekā ca nāḍyaḥ santi । tāsām ekā mūrdhānām api nisr̥tā। tayā urdhvam āyan amr̥tatvam eti। anyāḥ viṣvak utkramaṇe bhavanti ॥
kaṭhopaniṣad 2.3.16
There are one hundred one veins that merge from the heart. Only one of them goes to the moordha .
Jiva lives in the heart. When Mahapurursh leaves the body he goes out of the sushumna naadi that leads to brahm-randhra . Mahapurursh rides the sun rays to cross the brahmanda and goes to the abode of God.
Only Mahapurursh leave from moordha . Others according to their karma leave the body from eyes nose etc.
