Answer

In Jainism, breathing does not mean that air-bodied beings become part of your body system in a permanent way.

They are considered independent living beings present in air. When you inhale, you take in air, and because living beings may be present in that air, your breathing can disturb or harm them. But they are not treated like food or medicine that enters and stays in your organs.

Explanation

According to Jain dharma:

• Air-bodied beings (vāyukāyika jīva) are subtle living beings.
• They exist in and through air, but they are not your body.
• Ordinary breathing through the nose does not mean they become a part of your internal body system.
• If they are present in the air you breathe, they may be affected by contact, but that is different from “staying inside you” like a physical substance.

About prāṇāyāma:

• Jainism does not teach pranayama as a central spiritual practice in the same way some yogic traditions do.
• Gentle breathing awareness is one thing.
• Forceful breath control, strain, or practices done without care are not ideal from the Jain viewpoint of ahiṃsā.
• There is no standard Jain teaching that pranayama “pulls air beings inside” or “pushes them out” in a literal, mechanical way.

Spiritual Understanding

The main Jain concern is nonviolence and mindfulness.

So the spiritual approach is:

• breathe gently,
• avoid unnecessary force,
• remain aware that even very subtle life exists,
• and do not think of these beings as tools inside your body.

Jainism focuses on protecting life as much as possible, even in subtle forms.

Takeaway

Air-bodied beings are not your internal body parts. Breathing may affect them if they are present in the air, but they are not considered to be stored inside you. In Jain understanding, the right attitude is gentle, mindful, and nonviolent breathing.
