The Explanation of the Twelve-Month Caturthī Vrata
सुखं स्वप्यान्निशायां तु भूमावेव कृतार्चनः । व्रतस्यास्य प्रभावेण कामान्मनसि चिंतितान् ॥ १५ ॥
sukhaṃ svapyānniśāyāṃ tu bhūmāveva kṛtārcanaḥ | vratasyāsya prabhāveṇa kāmānmanasi ciṃtitān || 15 ||
Having performed worship, he should sleep comfortably at night upon the bare ground; by the power of this vow, the desires contemplated within his mind are fulfilled.
Sanatkumara (in discourse to Narada)
Vrata: none
Primary Rasa: bhakti
Secondary Rasa: shanta
It teaches vrata-niyama (discipline of a vow): after arcana (worship), adopting simplicity—such as sleeping on the ground—strengthens the vow’s efficacy, making the practitioner receptive to its promised fruits.
Bhakti is expressed not only through prayer but through embodied humility and regulated conduct; worship (arcana) followed by austerity-like simplicity is presented as devotion made steady through practice.
Ritual procedure (kalpa-style vrata-vidhi) is implied: perform arcana and maintain prescribed niyamas (such as sleeping on the ground), emphasizing correct observance rather than a technical Vedanga like Vyakarana or Jyotisha.
