If Vaishnavism is so popular and wide spread in India, the credit must go to Sri Ramanuja, who took advantage of the ecstatic outpouring of the south Indian mystics, the Alvars, and produced a highly logical philosophy of knowledge soaked in devotion as the easiest means of God-realization.
Avoid excessive merriment. A mind in that state never becomes calm; it becomes fickle. Excessive merriment will always be followed by sorrow. Tears and laughter are near kin. People so often run from one extreme to the other.
-Swami Vivekananda
