You are most likely asking about Sujeshtha / Sujyeshtha (सुजेष्ठा) – your spelling “sujayestha” matches this name.

Here is a simple Jain-dharma based introduction:

• Who was Sujeshtha?

Sujeshtha is described in Jain tradition as a daughter of King Chetaka of Vaishali. This makes her: - Sister of Queen Trishalā (mother of Bhagwan Mahavira) - Therefore, maternal aunt (māsī) of Bhagwan Mahavira.

• Family background

King Chetaka was a powerful and devout Jain ruler of Vaishali. His daughters (including Trishalā, Chellanā, Sujeshthā, etc.) are remembered in Jain stories as: - Highly cultured and graceful - Deeply inclined towards Jain dharma, ahiṃsā and spiritual values

• Life in Jain narratives

In Jain kathā-granthas and charitras, Sujeshthā is shown as: - A princess with strong faith in Jainism - One who rejects wrong beliefs and remains loyal to the teachings of the Tirthankars - Eventually renouncing worldly life and accepting dīkshā (initiation) as a Jain sādhuvī - Living under the guidance of senior sadhvijī (like Āryā Chandana in some accounts) with strict spiritual discipline

The details of her later spiritual achievements (such as whether she attained keval-jñān or not) are not uniformly detailed in all texts, so we should not add imagination. What is consistent is that she is remembered as a pious, principled Jain woman who chose the path of renunciation.

• Digambar / Shvetambar view

- Both accept her as being in Mahavira’s maternal family line. - The exact listing of sisters and relationships (who is counted as which sister, aunt, etc.) may differ slightly between sects and individual texts, but her connection to Trishalā and Chetaka is common.

• Spiritual message from her life

Jain tradition uses Sujeshthā’s story to show: - How even a princess, with all comforts, can turn towards vairāgya (detachment) - The importance of staying firm in Jain dharma, even when other paths are offered - That true greatness is in character and spiritual effort, not in position or luxury
