GOD realization is possible for all. The householders need not renounce the world, but they should pray sincerely, practice discrimination between the Eternal and the temporal and remain unattached. GOD listens to sincere prayer. Intense longing (vyakulata) is the secret of success in spiritual life - Sri Ramakrishna.
Many opportunities present themselves for the human beings to look towards GOD and to work towards the most elusive self-realization. There are very few in this world who can grab those opportunities and try crossing the ocean of samsara. Sri Ramakrishna, Pujya Acharya Sai Master are few examples of such people who went through the phases of life and still stayed untouched by the good and bad of such lives.
