The primary purpose of iaido is personal development and self-improvement through the practice of drawing, cutting, and resheathing a sword. Here are some key points regarding the purpose of iaido:

1. Mindfulness and Presence: Iaido cultivates a state of heightened awareness, concentration, and mindfulness. Practitioners aim to be fully present in the moment, focused on each movement and the immediate environment.
2. Discipline and Control: Iaido emphasizes discipline and control over oneself, both physically and mentally. Through repetitive practice, practitioners strive to develop precise and controlled movements, refining their techniques over time.
3. Mental Calmness: Iaido provides an opportunity to achieve a calm and focused state of mind, even in the face of stress or conflict. The practice aims to develop a sense of inner tranquility and the ability to remain composed under pressure.
4. Physical Conditioning: Iaido involves a series of precise and fluid movements that require coordination, balance, and core strength. Regular practice helps improve physical fitness, flexibility, and overall body control.
5. Understanding the Sword: Iaido practitioners seek to develop a deep understanding of the sword, its historical significance, and its use as a weapon. They study the different aspects of the sword, such as its balance, grip, and cutting edge, and strive to develop a harmonious connection with the weapon.
6. Preservation of Tradition: Iaido is rooted in centuries-old Japanese swordsmanship traditions. By practicing iaido, practitioners contribute to the preservation and promotion of this cultural heritage.

It's important to note that iaido is not focused on combat or sparring like some other martial arts. Instead, it is a contemplative and introspective practice that aims to develop personal growth, self-awareness, and a deep connection with the art of the sword.
