Here is a simple, tradition‑faithful gist of the Kalpa Sūtra and the main “paras” (episodes) it covers.

Kalpa Sūtra — overall gist (Śvetāmbara tradition)

• What it is: A revered Śvetāmbara Jain scripture traditionally recited in Paryuṣaṇ. It has three parts: Jina‑caritra (lives of the Tīrthaṅkaras, with special detail on Bhagvān Mahāvīr), Sthavirāvalī (lineage of ācāryas after Mahāvīr), and Sāmācārī (rules of conduct for ascetics, especially during the rainy season).
• Purpose: To inspire right faith and conduct by remembering the pure lives of the Tīrthaṅkaras, to preserve the guru‑paramparā, and to guide monastic discipline during Cāturmās.
• Authorship/tradition note: Traditionally attributed to Ācārya Bhadrabāhu (Śvetāmbara view). Digambar tradition does not treat the Kalpa Sūtra as canonical and does not recite it during Paryuṣaṇ; they observe Daśalakṣaṇa separately.

Gist of the main paras (episodes) in the Jina‑caritra of Mahāvīr (Śvetāmbara)

• Auspicious descent: The final decision of the soul of Mahāvīr to take birth for the uplift of beings; heavenly celebration.
• Conception and transfer: Conception and embryo‑transfer by Hariṇaigameṣin to Queen Triśalā of the Ikṣvāku line (Śvetāmbara narration). Note: Digambar texts do not accept the embryo‑transfer episode.
• Fourteen auspicious dreams: Queen Triśalā’s 14 dreams foretelling the birth of a Tīrthaṅkara and the king’s interpretation.
• Birth and rejoicing: Birth at Kuṇḍagrām; celestial and worldly festivities; naming as Vardhamān; early signs of extraordinary fearlessness and restraint.
• Householder life with inner detachment: Ideal conduct amidst royal comforts; gradual deepening of vairāgya.
• Great renunciation (dīkṣā): At the age of 30, performing keśa‑loñca (plucking of hair) and accepting mendicancy; vows of perfect non‑violence and restraint.
• Years of severe sādhanā: Long period of austerities, silence, equanimity amidst insults and hardships; perfect control over passions (kaṣāyas).
• Kevalajñāna (omniscience): Attainment of all‑knowing consciousness; establishment of the four‑fold Saṅgha; beginning of universal teaching (divya‑dhvani).
• Gaṇadharas and Gaṇas: Appointment of the 11 Gaṇadharas (with Gautama Svāmī as principal) and organization of disciples.
• Preaching of Dharma: Right faith, right knowledge, right conduct; emphasis on ahiṁsā, aparigraha, and self‑discipline for liberation.
• Nirvāṇa of Mahāvīr: Final liberation at Pāvāpurī on Kārtika amāvasyā; worshipful remembrance by the Saṅgha.

Gist of paras related to other Tīrthaṅkaras (as given briefly in Kalpa Sūtra)

• Ṛṣabhadeva (Ādinātha): The first Tīrthaṅkara; begins the dharma‑tradition for the current time‑cycle.
• Pārśvanātha: The 23rd Tīrthaṅkara; renowned for compassion and the four‑fold restraint; his life is summarized to frame Mahāvīr’s advent.
• The remaining Tīrthaṅkaras: Their names and essential milestones are remembered to honor the complete lineage of the 24.

Sthavirāvalī — gist

• Lineage after Mahāvīr: From Gautama Svāmī to Sudharman, Jambu Svāmī, and successive ācāryas; it preserves the pure transmission (guru‑paramparā) and reminds the Saṅgha of unbroken stewardship of the doctrine.

Sāmācārī — gist (rules of conduct, especially for Cāturmās/Paryuṣaṇ)

• Staying in one place during rains; carefulness (saṁiti), vigilance (gupti), and non‑injury to even the smallest life.
• Austerities and daily discipline: Fasting, alms conduct, scriptural study, meditation, confession/atonement (pratikramaṇa, prāyaścitta).
• Purity in speech and livelihood, restraint of senses, humility towards teachers, and harmonious Saṅgha living.

Important tradition notes

• Śvetāmbara: Kalpa Sūtra is publicly recited in Paryuṣaṇ; special focus on Mahāvīr’s janma‑kalyāṇak and nirvāṇa episodes; inclusion of the embryo‑transfer narrative.
• Digambar: Do not recite Kalpa Sūtra; emphasize Daśalakṣaṇa during the same period; embryo‑transfer account is not accepted in Digambar texts.
