कदाचिदभवद्धृष्टिः शीतवातसमन्विता |
मेघनादकृतारावा विद्युद्वल्लीसमुज्ज्वला ||
घोरेण तमसाक्रान्तं पङ्क संयुक्तमार्गकम् |
पतद्भूरुहसङ्कीर्णमभवद्यमुनावनम् ||
Once it poured down cats and dogs accompanied by thunder, lightening and chill winds. At that time Shri Brindavan was very badly affected. It was encircled by darkness. It was slushy all over and hence the path was eroded. Many trees were lying haphazard on the ground.

युक्तं नियममास्थाय दृढनिष्ठो यथारुचि |
कृष्णमाराधयेन्नित्यं सा परा भक्तिरुत्तमा ||
प्राणांस्त्यक्त्वापि नियमं पालयेत् सुदृढव्रतः |
प्रीतो भवति गोविन्दो भक्तस्य दृढनिष्ठया ||
Each one should firmly engage in some routine sevice to Shri Krishna suited to one's taste and capacity. This is the characteristic feature of true devotion. A staunch devotee should not give up his routine even at the cost of his life. Shri Govinda gets gratified only to find such sincere involvements on the part of His devotees.
