It is very strange that the Sanskrit word "Isha" becomes the root of half of the problems of the world / humanity when taken out of the depth of Vedant contemplative framework.
Isha, Sanskrit word for "Ishwara" - the formless God becomes Isha, Ishu, Josua etc of Christianity and wrecks havoc on humanity so far removed from the intended use if Isha under Hinduism. What a strange thing... Name is Hindu but all other things are Abrahamic - his being a Massiha - the massanger to begin with militates aginst very basics of Vedanta philosophy wherein Isha is :
ईशावास्यं इदं सर्वं यत् किञ्च जगत्यां जगत।
तेन त्यक्तेन भुञ्जिथाः मा गृधः कस्य स्विद् धनम् ॥१॥
Isha is everywhere and not only in Jerusalem !!
