The Guru is like a engine of the train.

The train has fixed destination. It never looses path neither the direction. The passenger sitting in the train is rest assured of him/her reaching the destination safely and surely. No one doubts the train, puts all the trust and faith in the train on securing the seat. But the train never has any other agenda, but to safely take the passengers to the destination
Guruji Naushir has always given this example. He says Guru is like the train, all his life leading people to divinity. Anyone can board the train who wishes to reach the final destination. Some get down before the time, some might join halfway, those who stay will surely reach the destination.

Baba Nityananda of ganeshpuri has quoted the same in his discourse, while guiding the disciples

He emphasised spiritual practices. But he also emphasised the importance of one’s worldly responsibilities, one’s dharma. He said that first we should pay attention to our duties and only when they are handled, dedicate ourselves to sadhana and spiritual practices.

Mainly, he spoke about guru’s grace and guru kripa. He said that surrender to the guru is ultimate on this path. Once the guru takes your hand, he will never let you down. The guru's concern for his disciples is comparable to that of a tortoise to its young ones. It is believed that although the tortoise floats in the deep sea, its attention is always on the eggs lying on the shore (Kurma Dristhi). Its intense concern and love for the young ones soon leads the eggs to hatch and guides the newborn safely to sea. Even if the tortoise is not there at that time.

He said, 'This One is the engine driver. Attach your bogie (wagon) to the train driven by this One and rest assured that you will be delivered'.

 'Do one’s duty first, with full trust and faith in one’s Guru and strive for excellence in whatever one attempts'. While at work, fix the mind at his feet just as a woman while going about her household chores, constantly thinks of her paramour. Chant the Gurumantra, worship one’s Gurudeva and meditate whenever one finds time.

 The world will not have any influence on such a person. One who pursues such a life shall receive all honour and fame without asking. While taking care to remain merged in namsankritan and continuing one’s sadhana, wait for the Guru’s infinite grace to dawn within the mind. This is what Guru Kripa is all about.

Once that happens, the Guru will guide the follower in his/her sadhana and shaktipat will happen automatically. Surrender to him like a child that trusts its parents. The Guru will ensure that sadhana goes on and the Kundalini shakti rises in all glory and the Self eventually becomes one with Shiva, the eternal principle.
