The "Kṛṣṇa" name means the highest pleasure. It is confirmed that the Supreme Lord is the reservoir, is the storehouse of all pleasure. We are all hankering after pleasure. Ānandamayo 'bhyāsāt (Vedānta-sūtra 1.1.12). The living entities or the Lord, because we are full of consciousness, therefore our consciousness is after happiness. Happiness. The Lord is also perpetually happy, and if we associate with the Lord, cooperate with Him, take part in His association, then also we become happy. The Lord descends on this mortal world to show His pastimes in Vṛndāvana full of happiness.
