Vedanta from nature - Airport

To catch a flight, one must enter the airport, deposit our luggage and then board the flight, similarly to attain the supreme abode of Sri Hari, Bhakthi is the flight we must catch. We cannot enter a railway station and look for a flight. Similarly to get Bhakthi we must follow the authorized process of Varnashrama Dharma to be performed as a Karma Yogam as indicated in our scriptures. We cannot manufacture or concoct our own means to liberation. Once we enter the airport automatically we get a chance to unload and deposit our luggages  to board the flight, similarly by the performance of our sva Dharma Karma Yogam; our eternal papa, punya karma which acts as an obstacle to get bhakthi gets destroyed. Thus free from papa  - punya karma we get Bhakthi. Thus our road to liberation is open.
