Answer

Kheer Samudra Tap is a Jain tapasya associated with devotion, self-control, and purification of karma. It is especially known in Jain tradition as a form of austerity where the devotee observes disciplined fasting and limited intake, traditionally connected with kheer in a regulated manner.

History

Sorry, I can only provide information that is clearly established within Jain tradition.

A detailed, universally accepted historical origin of Kheer Samudra Tap—such as the exact first person who performed it, exact time period, or scriptural source—is not clearly established across all Jain traditions.

However, it is generally understood within Jain practice that:

• Tap has been an important part of Jain Dharma since ancient times.
• Jain scriptures greatly emphasize austerity for reducing karmas and strengthening detachment.
• Different tapas such as fasts, Ayambil, Upvas, Varshitap, Oli, and other disciplined observances developed within Jain religious practice under the guidance of Acharyas, Sadhus, and Sadhvis.
• Kheer Samudra Tap is followed by some devotees as a devotional and disciplined tapasya, usually under proper religious guidance.

Spiritual Understanding

In Jain Dharma, the purpose of any tap is not taste, pride, or display. The true purpose is:

• Control over senses
• Reduction of attachment to food
• Purification of karma
• Growth in humility and discipline
• Strengthening of right faith and devotion

Takeaway

Kheer Samudra Tap should be understood mainly as a Jain austerity for spiritual purification. Its exact historical origin is not clearly established, so it is best performed only with guidance from a knowledgeable Jain Guru, Sadhu, Sadhvi, or trusted religious authority.
