(Kadamba Kanana Swami, April 2009, Durban, South Africa, Ratha Yatra Lecture)

So it is said, in this way, we must fill our consciousness completely to the top with Krsna. Then there are still small, small spaces between the stones – those you must fill up with little stones, with smaller things – with refined things, with more refined ways of meditating on Krsna, remembering Krsna and appreciating Krsna. Then still finer, in between the big stones and small stones, there is still a little space to be filled up with sand. In this way, fill until there is no space left.
So not only must our Krsna conscious increase but the smaller stones also mean that we must start paying more attention to the detail and do it right!
