Answer

If you are doing upvas and have a headache at the back of the head, first sit or lie down quietly and rest. Do not force the body beyond its capacity.

You can try:

• Rest in a calm, quiet place.
• Avoid heat, loud noise, bright light, and too much activity.
• Sit with a straight but relaxed posture.
• Do slow, gentle breathing.
• Do peaceful Navkar Mantra jaap mentally.
• If permitted in your upvas rules, take warm water or boiled water.
• Gently relax the neck and shoulders; avoid strain.

Important

If the headache is severe, increasing, unusual, or comes with vomiting, dizziness, weakness, blurred vision, fever, or neck stiffness, you should inform an elder and seek medical help. In Jain Dharma, protecting life and health is important. Tapasya should be done with awareness, not stubbornness.

Spiritual Understanding

Upvas is meant for self-control, inner purification, and reducing attachment, not for harming the body. If the body is suffering strongly, it is better to take guidance from elders, guru, or a doctor.

Takeaway

Rest, remain peaceful, do Navkar Mantra, avoid strain, and take permitted water if your upvas allows. If the pain becomes strong or worrying, do not ignore it.
