Answer

In Jain usage, “Khanan” means digging or excavation, and “Khanan Vidhi” is the ceremonial groundbreaking done before constructing a Jain temple or Derasar. ( rekhtagujarati.org)

If you meant “Khanan mass tap,” that does not appear to be a standard Jain tapasya name; it sounds more like a reference to Khanan Vidhi. ( rekhtagujarati.org)

Explanation

Khanan Vidhi is performed with auspicious rituals such as poojan, aarti, and other ceremonial steps, and it marks the formal start of temple construction. ( jainqq.org)

Spiritual Understanding

In Jain tradition, this ceremony is considered a sacred beginning. It is done with reverence so that the new Derasar or Jain center starts in a pure, auspicious manner. ( jainqq.org)

Takeaway

So, in simple terms, Khanan Vidhi = Jain ground-breaking ceremony, not a fasting tap. ( jainqq.org)
