Preksha meditation [Preksha Dhyana] is a popular meditation technique of Jainism . It was formulated by the tenth Spiritual head of Terapanth Shvetambara Jain Acharya Mahaprajna in the middle of the 20th century on the guidance of Acharya Tulsi. It is the combination of knowledge from ancient religious books, modern science and experience. Acharya Mahaprajna practised the technique on himself for nearly 30 years before presenting it to the general mass in modern languages. With his editorial team consisting of ascetics of the Terapanth order, he matched it with modern science and began to present it in public in the 1970s. Since then, the aim of Preksha Meditation is to continue serving humanity. The word Preksa is derived from the root ‘iksa', which means 'to see'. When the prefix 'pra' is added, it becomes pra + iksa = preksa, which means to 'perceive carefully and profoundly.'
