浄めに用いる土の量は、新鮮なアーマラキー（ダー トリー）の実一つに等しいと説かれる。同じ量は、あらゆる供物にも、またチャンドラー ヤナの誓戒における一口一口にも当てはまる。東または北に面し、清らかな地に正しく坐して、触れ・啜りの作法を行うべきである。もし（適切な土や水が）得られぬときは、籾殻、炭、骨灰、あるいは灰を代用してよい。

Tirtha: Kāśī-kṣetra (ritual conduct context)
Type: kshetra
Scene: A ritual teacher demonstrates a measured clod of earth the size of a fresh āmalakī; beside him, a vrata-observer counts Cāndrāyaṇa morsels; a clean mat on the ground is oriented east/north; a small tray shows substitutes—chaff, charcoal, bone-ash, ash—labeled for scarcity situations.
FAQs
Purification is governed by precise dharmic measures and mindful orientation, yet dharma also provides practical substitutes in scarcity.
The instruction belongs to the Kāśī Khaṇḍa’s ritual framework; it does not single out a named tīrtha in this verse.
Earth for cleansing is measured by a fresh āmalakī; the same standard applies to offerings and Cāndrāyaṇa morsels; face east or north on clean ground; substitutes like chaff/charcoal/ashes are allowed if needed.
