Call upon God. He will help you. He will respond and He Himself will be your Guru. He will guide you. He will always be at your side. Think God, see God, hear God, drink God, love God. That is the easy path, the royal road to your goal of breaking ignorance and the realisation of your true nature, which is one with God. (CWBSSB, p. 176)
Take up the Name of God, any of the innumerable Ones, any that appeals to you most, and the Form appropriate to that Name, and start repeating it from now on; that is the royal road to ensure joy and peace. That will train you in the feeling of brotherhood and remove enmity towards fellowmen. (SSS Vol.1)
Only those who have recognised My Love and experienced that Love can assert that they have glimpsed My Reality, for the path of love is the royal road that leads mankind to Me. (SSS Vol.12)
Rectitude is the Royal Road to the Seat of God. (SSS Vol.2)
Do not condemn the mind as a monkey, etc. It is a fine instrument with which you can win either liberation or bondage. It all depends on how you manipulate it. It will carry out your orders to the minutest detail. It will lead you, if you so desire, along the royal road, right up to the door of Realisation. Or it will make you wander about in the blind alleys, where every step lands you in dirt. (SSS Vol.2)
