What vow can an ordinary householder take for Cāturmāsa?

one small, steady restraint or practice for the four months — giving up one food, a daily reading, extra japa or a weekly fast.

Cāturmāsa runs from Devśayanī Ekādaśī to Prabodhinī Ekādaśī. Sannyāsīs stay in one place, and householders traditionally take a niyama, a personal vow, for the period. The Purāṇas list many: giving up a favourite food like sugar, ghee, rice or a vegetable; eating once a day; sleeping on the floor; silence at meals; daily Gītā or Rāmāyaṇa reading; a fixed number of mālās; lighting a lamp to Viṣṇu.

Choose one thing you can actually keep for four months, ideally connected to a habit you want to change. Many people give up something like tea, sweets, social media in the evening, or eating out, and add one daily devotional act.

Take the saṅkalpa on Devśayanī Ekādaśī before Viṣṇu, and on Prabodhinī Ekādaśī offer what you gave up and give a little dāna. A small vow kept is better than a large one dropped.
