A householder, or 'grihastha' in Hinduism, is an individual who is in the second stage of life in the ashrama system, which emphasizes the importance of family, social responsibilities, and the pursuit of dharma (righteous living). This phase of life is characterized by marriage, raising children, and fulfilling duties to society and the household. It represents a critical period where individuals engage actively with the world while balancing spiritual growth and worldly responsibilities.
