Yajurveda Chapter IV Verse 21
I have mentioned it earlier also and I mention it now too. Your basic problem is that you have chosen a very wrong book as your reference - Devi Chand of Ary Samaj. See here is what I get from Ralph Griffith (and that is the reason Secred-Texts.com has not selected Devi Chand's translation). Arya Samaj has done a totally incorrect translation of YajurVeda - It is hugely misleading.
Ralph Griffith (White YajurVeda Chapter VI, Verse 21):
Go to the sea. All-hail! Go to the air. All-hail! Go to God Savitar. All hail!
Go thou to Mitra-Varuna. All-hail! Go thou to Day and Night. All-hail!
Go to the Metres. till-hail! Go to Heaven and Earth. All-hail!
Go to the sacrifice. All-hail! Go to Soma. All-hail!
Go to the heavenly ether. All-hail! Go to Vaisvânara
Agni. All hail! Bestow upon me mind and heart.
Thy smoke mount to the sky, to heaven thy lustre.
Fill thou the spacious earth full with thine ashes.
There is no Geography, History, Astronomy, in this. I do not know where from the Arya Samaj people get that! Dump Devi Chand's book. Read something sane.
