Moksha means the soul getting free from the cycle of birth and death. But getting moksha is not easy. A person who wants to get moksha after death has many questions , doubts and challenges. That's why hindu scriptures explain the great importance of gurus.
Guru is not an ordinary teacher. They help people to understand life, answer their doubts and help them to get spiritual life. For centuries, the bond of guru and disciple has been the most pure bond.
