Answer

If you mean Saubhāgya Pañcamī Tap — sometimes loosely called “Suhag Tap” — it is a Jain observance connected with Rājīmatī (Rājul) and the story of Lord Neminātha (Nemi). It is associated with the day when Nemi and Rājīmatī were to be married, and when Nemi renounced worldly life. ( jainpedia.org)

Explanation

In Jain tradition, this tap is linked with the recitation of Nemanāth Saloko, which is done on Śrāvaṇ bright fifth. Jainpedia notes that this observance is believed to bless a woman with a long and healthy marriage, and the recitation is also commonly performed at weddings for auspiciousness. ( jainpedia.org)

The deeper meaning is not only “marital happiness,” but also virtue, fidelity, restraint, and remembrance of renunciation. Rājīmatī is remembered as an ideal Jain woman, and her story is closely tied to the values of devotion and detachment. ( jainpedia.org)

Spiritual Understanding

This tap reminds a Jain household that true saubhāgya is not only external prosperity, but also pure conduct, inner peace, and auspicious living. In Jain understanding, worldly life is always seen alongside the higher ideal of renunciation, which is why the Rājīmatī–Nemi story is so spiritually meaningful. ( jainpedia.org)

Takeaway

So, Suhag Tap / Saubhāgya Pañcamī Tap is a Jain fast or vow connected with auspicious married life, Rājīmatī’s virtue, and Nemi’s renunciation. It is a sacred reminder that a blessed life should be rooted in dharma, restraint, and devotion. ( jainpedia.org)
