The Explanation of the Twelve-Month Caturthī Vrata
अयाचितोपवासाभ्यां तृतीयकचतुर्थके । एवं क्रमेण विधिवच्चत्वार्यब्दानि मानवः ॥ ५६ ॥
ayācitopavāsābhyāṃ tṛtīyakacaturthake | evaṃ krameṇa vidhivaccatvāryabdāni mānavaḥ || 56 ||
第三年と第四年には、乞わずして得た食(アヤーチタ)にて生きることと、断食(ウパヴァーサ)とを修すべし。かくして順次、定められた法にかなって正しく守れば、人は四年(の誓戒)を成就する。

It emphasizes tapas guided by vidhi (proper rule): spiritual progress is strengthened when austerity is gradual, ethical, and sustained over time rather than impulsive.
By prescribing regulated restraint (fasting and contentment with unsolicited food), the verse supports purity and steadiness—qualities that make the mind fit for sustained devotion and remembrance.
Kalpa (ritual procedure) is implicit: it outlines a sequential vrata-krama and insists on विधिवत्—performing observances according to prescribed rules and stages.
