With devotion steeped in love and affection, the yogi should meditate within the core of his heart upon the laughter of Lord Visnu. The laughter of Visnu is so captivating that it can be easily meditated upon. When the Supreme Lord is laughing, one can see His small teeth, which resemble jasmine buds rendered rosy by the splendor of His lips. Once devoting his mind to this, the yogi should no longer desire to see anything else.
