A person who does not express his mind to everyone, or whose mental activity and plan of action are very difficult to understand, is called grave. After Lord Sri Krsna had been offended by Brahma, Brahma prayed to Him to be excused. But in spite of his offering nice prayers to Krsna, Brahma could not understand whether Krsna was satisfied or still dissatisfied. In other words, Krsna was so grave that He did not take the prayers of Brahma very seriously. Another instance of Krsna's gravity is found in connection with His love affairs with Radharani. Krsna was always very silent about His love affairs with Radharani, so much so that Baladeva, Krsna's elder brother and constant companion, could not understand the transformations of Krsna on account of His gravity.
