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.
