You love your wife, and she loves you, but if she is hungry, you cannot eat for her, and if you are hungry, she cannot eat for you despite the fact that you love each other dearly. Spiritual hunger is like that. Each man must seek and appease that hunger according to his faith. Even though Swami tries to explain, you do not grasp it. It is only through experience that you will come to it. (CWBSSB, p. 687)
In the spiritual field, you must be sincere. Do not pretend and deceive yourself and others. (SSS Vol.2, p. 65)
Act, and then, advise; practice first, precept second. Work is for the physical level; worship for the mental, and wisdom for the spiritual. (SSS Vol.8, p. 70)
