There are many processes for delivering the living entity from this life of entanglement. Generally it is summarized in the process of meditation, performances of great sacrifices and worshiping the Lord in the temple. But in this Age of Kali Yuga nobody can meditate perfectly, neither they have sufficient resources for performing great sacrifices, neither they have tendency to attend spiritual services in the temple, churches, or mosques or any such sanctuaries. Therefore, in the Brhad Naradiya Puranam it is stated that none of these three principles of spiritual upliftment is possible to perform in this Age of Kali. Therefore, the only possible means of spiritual realization is chanting the Holy Name of God or Krishna or Rama.
