One of the iconic elements is the use of the Chakram in the Sikh martial tradition.

In the mid-19th century, the Nihang Sikh warriors adopted unique conical turbans which carried multiple chakrams—circular steel blades that could be thrown with lethal accuracy. These edged weapons became a distinct feature of the Akali warriors, who could hurl them effectively in combat. The Sikh martial arts evolved into a formidable form, blending unarmed combat techniques with weapon mastery.

This tradition is also linked to the mythological use of weapons, as described in the great Indian epic, Mahabharata. The god Lord Krishna wielded the Sudarshana Chakra, a powerful spinning disc that was said to be capable of destroying any opponent and even re-positioning itself after an attack. It is revered as one of the most powerful weapons ever created, representing the mastery of celestial combat in Indian tradition.

Combat Techniques and Comparisons to Other Martial Arts

Sanathana Sastra Vidya’s unarmed techniques include dynamic movements and forms that resemble the fundamental principles seen in modern martial arts like Tai Chi and Wing Chun. These systems emphasize the redirection of an opponent's force, precision strikes, and strategic use of body mechanics to overcome stronger foes, much like Taichi's energy flow and Wing Chun's close-range combat strategies. The Indian forms focus extensively on power diversion techniques, allowing practitioners to effectively channel their opponent's energy for both defense and counterattack.

What stands out is the application of these techniques in real combat scenarios, offering practical skills for personal safety. Unlike sports-oriented martial arts, Sanathana Sastra Vidya focuses on unpredictable street attacks, making it highly useful for self-defense in chaotic, real-life situations.

Conclusion: Preserving Ancient Wisdom

Sanathana Sastra Vidya is a testimony to India's rich martial arts heritage—one that blends mythology, practical combat techniques, and a deep understanding of the human body.
