Based on Bhagavad Gita Chapter 06, Text 26
“Yet again the mind has gone astray. How many times can I keep struggling against it?” This is our common reaction when we try to fix the mind on Krishna, but it strays off to thoughts of immoral pleasures and offensive actions. When the slippery mind keeps thwarting our efforts repeatedly, we may get discouraged,feeling that we will never be able to devote ourselves internally to Krishna.
Significantly, Gita wisdom anticipates and addresses our concern.
One of the most stimulating features of Gita wisdom is its adeptness, even proactiveness, in catering to our spiritual concerns at our level. The Bhagavad-gita (06.26) encourages us by stating that, no matter how often the mind strays awayfrom Krishna, we have the power to not let it stay away. This verse contains the wordyato twice (yato yato nishchalati). This double occurrence hints at the two circumstances in which the mind may wander off: at various times and in different places. Whenever (yato) or wherever (yato) the mind strays off, the Gita encourages us to bring it back to Krishna.
