Atma Vichara and Pancha Mukha Hanuman
Pancha = five. Mukha = face. Thus Pancha Mukha Hanuman is the five faced Lord Hanuman. The five faces are those of Varaha, Garuda, Hanuman, Narasimha and Hayagriva.
When a spiritual aspirant does sincere atma vichara under the guidance of a Sathguru, the Lord of Self Enquiry, Pancha Mukhi Hanuman, reveals the divine truth to that seeker through His five faces. This Siddha spiritual insight was taught to Sathguru Venkataraman by his Sathguru Sri La Sri Idiyaappa Siddha Easar.
Through three faces, Lord Panch Muka Hanuman, reveals the soul's past, present and future and its life in these three phases in a sthoola or concrete, material body.
Through the fourth face, Lord Pancha Muka Hanuman gives instruction to the soul on transcending the aforementioned three phases and thus dissolving its limited individuality in the limitless universality of the Lord through the path of saranagathi, i.e., perfect surrender to the Divine Will.
Through the fifth face, Lord Panchmukhi Hanuman initiates the sincere soul into this sublime process.
Thus Lord Pancha Mukha Hanuman is the Divine Helper of all those who seek atma gnana. He ensures our enthusiasm during the atma vichara process and motivates us on the road to atma gnana. He helps us find the correct answer to the "Who am I?" question.
All those who do atma vichara and all those who seek atma gnana should pray to Lord Panch Mukha Hanuman and sincerely seek His blessings. May He help us in our quest for atma gnana!
