the dream of paini mata and the diksha story of hemchandraji

In the Jain story of Acharya Hemchandra, his mother is Pahini Devi. When she was pregnant, she had a beautiful dream. She told it to Acharya Devsuri, and he interpreted it as a sign that she would give birth to a son who would make great progress in spiritual knowledge, intuition, and conduct. ( jainbelief.com)

After his birth, the child was named Changdev. Later, the same guru recognized his deep spiritual potential and accepted him into the monastic path. In Jain tradition, this is remembered as the beginning of the life of Acharya Hemchandra, who became one of the great Jain scholars and saints. ( jainbelief.com)

Diksha story of Hemchandraji: he was initiated into Jain monkhood by Acharya Devsuri and received the name Somchandra / Somachandra before later becoming known as Hemchandra. Jain sources place this initiation in his youth, and his later life became famous for scholarship, restraint, and service to Jain Dharma. ( en.wikipedia.org)

In simple words, the dream of Pahini Devi was seen as an auspicious sign of a महान आत्मा, and Hemchandraji’s diksha became the fulfillment of that spiritual indication.
