They say the Lord’s mercy is coming down like the sunlight, and the Guru’s mercy is like the lake, and our spiritual life is like the lotus. The lotus is floating on the water, and getting the sunlight…then everything goes very nice.
You need the Lord’s mercy, otherwise the lotus doesn’t open. But we needs the Guru’s mercy, if there’s no water, then the lotus is just in the sunlight without any water, it will dry out.
So we need the mercy of the Lord and we need the mercy of His devotee. It says, by Krishna’s mercy one gets Guru, and by Guru’s mercy one gets Krishna.HH Jayapataka Swami Lecture: SB 2.7.46 2005 Srirangam
