This is a most charming way of stating the truth revealed in the Isha Upanishad.
अन्धं तमः प्रविशन्ति येऽविद्यामुपासते ।
ततो भूय इव ते तमो य उ विद्यायां रताः ॥९॥
9) Into a blind darkness they enter who follow after the Ignorance, they as if into a greater darkness who devote themselves to the Knowledge alone.
अन्यदेवाहुर्विद्यया अन्यदाहुरविद्यया ।
इति शुश्रुम धीराणां ये नस्तद् विचचक्षिरे ॥१०॥
10) Other, verily,9 it is said, is that which comes by the Knowledge, other that which comes by the Ignorance; this is the lore we have received from the wise who revealed That to our understanding.
विद्याञ्च अविद्याञ्च यस्तद् वेदोभयं सह ।
अविद्यया मृत्युं तीर्त्वा विद्ययामृतमश्नुते ॥११॥
11) He who knows That as both in one, the Knowledge and the Ignorance, by the Ignorance crosses beyond death and by the Knowledge enjoys Immortality.’
Practically it means that instead of leaving the worldly life and the knowledge it brings to pursue the spiritual one should deepen and widen this knowledge that is given to us here by the mind and senses. If we do this, going into the depth of everything and then we will discover the bridges between the spiritual and the material.
On the other hand if we jump from one to the other then we get disconnected from this reality which has its own truth concealed within.
It means that instead of this or that it should be this and this. Instead of taking medicines or leaving it to the Divine we should take the medicine and leave it to the Divine as well as try to find the deeper causes and heal them.
So too with everything in life.
