Jagadguru Shankaracharya Swami Bharati Krishna Tirtha, born as Venkatarama Krishna Bhatt in 1884, led a life dedicated to spiritual pursuits and service. While information about his personal life is relatively limited, it is known that he renounced worldly life to embrace a monastic path. Swami Bharati Krishna Tirtha became a disciple of Shankaracharya Swami Brahmananda Saraswati and succeeded him as the 33rd Shankaracharya of the Sringeri Sharada Peetham in Karnataka, India, in 1921.

As a Shankaracharya, his primary focus was on spiritual and religious matters, contributing to the revival and enhancement of the Sringeri Sharada Peetham. He was deeply committed to the teachings of Advaita Vedanta, a philosophical tradition emphasizing the non-dual nature of reality.

Swami Bharati Krishna Tirtha was also known for his interest in Vedic mathematics, and he wrote extensively on the subject, aiming to preserve and promote traditional Indian mathematical knowledge. His works on Vedic mathematics have been influential in bringing attention to ancient Indian mathematical techniques.

Swami Bharatikrishna Tirtha, in his book "Vedic Mathematics," presents 16 Sutras (aphorisms) that outline mental calculation strategies based on the Vedas. These Sutras cover a wide range of mathematical operations and provide concise methods for solving mathematical problems. Here are the 16 Sutras:

• Ekadhikena Purvena: "By one more than the previous one."
• Nikhilam Navatashcaramam Dashatah: "All from 9 and the last from 10."
• Urdhva-Tiryagbyham: "Vertically and crosswise."
• Paravartya Yojayet: "Transpose and adjust."
• Shunyam Saamyasamuccaye: "When the sum is the same, that sum is zero."
• Anurupyena: "Proportionately."
• Sankalana-vyavakalanabhyam: "By addition and by subtraction."
• Puranapuranabyham: "By the completion or non-completion."
• Chalana-Kalanabyham: "Differences and Similarities."
• Yaavadunam: "Whatever the extent of its deficiency."
• Shesanyankena Charamena: "The remainders by the last digit."
• Shunyam Anyat: "Zero is the other."
• Anurupye Shunyamanyat: "If one is in ratio, the other is zero."
• Sopantyadvayamantyam: "The ultimate and twice the penultimate."
• Ekena Sutena Cha: "By one less."
• Gunitasamuchyah: "The product of the sum."

These Sutras provide efficient and quick methods for solving mathematical problems, making arithmetic calculations more streamlined and accessible. Keep in mind that understanding and applying these Sutras may require some practice and familiarity with the techniques outlined in Swami Bharatikrishna Tirtha's work.

Jagadguru Shankaracharya Swami Bharati Krishna Tirtha passed away in 1960, leaving behind a legacy of spiritual guidance and contributions to Vedic knowledge. His life remains an inspiration for those seeking spiritual enlightenment and a deeper understanding of traditional Indian philosophy.
