It serves as a centre where the religious implies and sentiments of the people find a nature outlet. Worshipping Gods in Temple infuse divinity and purity in the heart of devotee. The Temple provides a link between man and God and the earthly life and divine life. The idea of God and the very purpose of veneration aroused a real zeal for worship. Since Plants, Trees and Groves were of great use, the ancient Tamils preferred them as suitable objects of worship. Tamils believed that gods used to raised in the hallows of Trees. Alamar Kadavul, Alamar Celvar and Kadampar Celvan clearly indicate the association of gods with Trees.Besides, many other Trees like “Arasu” (pepal) Pala (jack) Vanni, etc, were worshipped as the abodes of spirits and gods. These help up suggest that the practice of worshipping Trees as abodes or resting places of gods was in vogue among the early Tamils.
