In this perceptive work, Dr. Harish Dhillon highlights the lives and times of the ten Sikh Gurus, beginning with Guru Nanak, who founded Sikhism in 1469 and ending with Guru Gobind Singh, who established the Khalsa Panth in 1699. It throws light on how the Gurus acquired profound knowledge and wisdom, which they sought to pass on to the common people through their teachings. Their life histories show how they sincerely practised what they preached and how they led by example.

Apart from these, it recounts the enormous sacrifices the Gurus made to keep the faith going. In addition, the book gives elaborate details on how Sikhism has evolved over the centuries.
