• • Thuckalay Pir Muhammad Appa**, also known as *Birappa* and affectionately called ‘Appa’ by people of all castes and religions, was a revered Sufi Siddha whose wisdom songs are considered a priceless treasure for humanity and the Tamil language. Born into a weaving family in Thuckalay, his spiritual journey and contributions have left an indelible mark on history.

Pir Muhammad was born in Thuckalay to a weaving family and worked alongside his father in their trade. Known as *Birappa* during his early years, his heart gravitated towards the pursuit of knowledge and inner truth. His preference for solitude and contemplation led him to compose 18,000 Tamil wisdom songs, inspiring generations.

The hill in Kerala's forest region where Birappa performed penance is known as *Birmedu*. The place, now recognized as a taluka, stands as a testament to his spiritual discipline.

Birappa maintained harmonious relationships with everyone, from the kings of Travancore to the common folk. He was renowned for his healing abilities and compassionate guidance, providing remedies for both physical ailments and spiritual challenges. His life was marked by inclusivity and unwavering devotion.

Thavagnani Pir Muhammad is regarded as one of the eighteen Siddhar. His dargah in Thuckalay, Kanyakumari district, is a place of veneration. Born in Tenkasi, Tirunelveli district, Pir Muhammad lived over three centuries, although the exact dates are uncertain, with his birth likely in the 16th or 17th century.

Pir Muhammad spent approximately 95 years practicing asceticism in the forests and mountains, including the Travancore kingdom. His spiritual training and meditation in Kerala gave rise to the village name *Peermedu*, honoring his legacy. Legends speak of his harmonious coexistence with wild animals during a 15-year period of deep meditation.

The kings of Kochi and Travancore sought his guidance. The king of Kochi, inspired by Peerappa's wisdom, renounced his throne to embrace asceticism. Similarly, the king of Travancore received divine blessings and wisdom from Peerappa.

Pir Muhammad is celebrated as a bridge between Sufi mysticism and Tamil Siddha tradition. His philosophical insight, encapsulated in the line, *"The mountain peak is small... Our mind's peak is big,"* reflects his spiritual elevation.

Pir Muhammad composed over 18,000 arutpas (songs of grace), including: - *The Milk of Wisdom* - *The Lock of Wisdom* - *The Praise of Wisdom* - *The Garland of Wisdom* - *Bismil Qur’an* - *The Hymn of Wisdom* - *The Joy of Wisdom* - *The Dance of Wisdom* - *The Eye of Wisdom* - *The Treasure of Wisdom*

His celebrated *Gnanarathna Kuravanchi*, part of the *Periya Gnanakovai*, consists of 66 verses unfolding philosophical ideas through a dialogue between a lion and a lioness.

His work *Gnanapuchchi* consists of 685 songs glorifying the virtues of God and emphasizing surrender to Him. Drawing inspiration from the Quranic verse, *"He it is who created everything on earth for you,"* it remains a testament to divine devotion.

The memorial festival of Pir Muhammad is celebrated annually on the 14th day of Rajab. A key highlight is the all-night recitation of *Gnanapukallachi*. The festival attracts people from diverse faiths, fostering unity and harmony between Tamil Nadu and Kerala.
