Shiva Lingam

Lingam is a sacred symbol that represents the union of Shiva and Shakti and the divine nature of the universe.
The Lingam is a representation of the Hindu god Shiva in his form of universal creative energy. The term Lingam comes from the Sanskrit linga, which means "symbol" or "marker". Lingam refers to the representation of Shiva as a pillar or column of light.
The Lingam is often represented as a vertical column with a vase-shaped base, called a yoni, which represents the female deity Shakti. Together, the Lingam and the Yoni represent the sacred union of Shiva and Shakti, the creation of the universe and the generating force of life, the sacred union of complementary male and female opposites.
The Lingam is worshiped during the ritual called "puja" with offerings of milk, honey, water, flowers and incense. The faithful turn to the Lingam to ask for protection, blessings and prosperity. The Lingam is also used as an object of meditation to help focus on the divinity of Shiva and to attain knowledge and enlightenment.
In the Hindu tradition, the lingam is revered as a symbol of fertility and creation, and is used in fertility and purification rituals. It is also used as an object of meditation, where the devotee concentrates on his form to achieve a state of oneness with the divine.
