Bhakti Vikasa Swami: Prahlada: both happy and unhappy [ 2009-01-21 ]
Prahlada Maharaja was happy and unhappy simultaneously. He felt happiness and transcendental bliss because of his being Krsna conscious, yet he felt great unhappiness for the fools and rascals who make elaborate plans to be happy in this material world.
