There is no Manglik (mangal dosha) or Manglik “sootra” in Jainism, including for the Sthanakvasi tradition. The concept of Manglik is part of Hindu astrology and not a Jain scriptural category. So, there isn't an English Manglik sutra to provide for Jain Sthanakvasi.

If you’d like Jain devotional content in English that is authentic to Jain teachings, I can share:

• The Navkar (Namokar) Mantra in English transliteration and its meaning.
• A simple explanation of what Jain prayers honor (Arihants, Siddhas, Acharyas, Upadhyayas, Sadhus/Sadhvis) and how they are used in daily practice.

Navkar (Namokar) Mantra in English (authentic Jain practice):

• Namo Arihantanam

I bow to the Arihantas, conquerors of inner enemies.

• Namo Siddhanam

I bow to the Siddhas, liberated souls who have attained salvation.

• Namo Ayariyanam

I bow to the Acharyas, spiritual teachers and leaders.

• Namo Uvajjhayanam

I bow to the Upadhyayas, who teach Jain scriptures.

• Namo Loe Savva-sahunam

I bow to all Sadhus and Sadhvis.

Meaning in brief:

• It is a universal salutation to the senior spiritual beings in Jainism, intended to remind the practitioner of the path to liberation and to cultivate humility, non-attachment, and piety. It does not reference planetary influences or astrological factors, which is separate from Jain practice.

If you want, I can provide a simple, clear English translation of a few other Jain prayers (like the Stavan or various stotras) that are commonly used by Sthanakvasi Jains, kept true to Jain meanings.
