The Essence of the Vibhutis 41-42

1 Gita Sloka  every day - Chapter 10 - Vibhuti Yoga - Sloka 42

Athava bahuna etena kim gyatena tava arjuna I

Vishtabhya aham idam kritsnam eka ashena sthitah jagat II sloka 42

अथवा बहुना एतेन किं ज्ञातेन तव अर्जुन I 

विष्टभ्य अहं इदं कृत्स्नं एक अशेन स्थितः जगत् II श्लोक 42

But what need is there, O Arjuna, for this detailed knowledge? I stand supporting the whole universe with a single fragment of myself (my power)

What use to you is this detailed knowledge taught by me? I sustain this universe with a infinitesimal fraction of my power -  this universe consisting of sentient and non-sentient entities, whether in effect or causal condition, whether gross or subtle. In such a manner that it does not violate my will in preserving its proper form, existence and various activities. As said by Bhagavad Parasara, "On an infinitesimal fraction of this energy, this universe rests".
