In plain words
Those devoted to God must have these two with them, firm faith and purity. If faith is not firm, if there is no purity at all, a man falls into a state of doubt and turns into a doubting Thomas. In such a life, what fruit can Bhakti give us? At every step we have nothing but doubts. Such a person cannot achieve even the least success. Firm faith is not merely Bhīma's strength of body, nor the strength of an elephant; one must have the strength of the intellect. That is firm faith. It comes only when you place pure Prema at the feet of God, even for a moment.
The worry that arises on earth over keeping sons and friends, over business and talk, the worry that always arises over wealth, grain, pleasure, fame and gain: if that same worry on earth were turned to beholding the lotus feet of Nanda's son, what worry would there be, O Lord, on the journey to the door of Yama's dreadful house?
For as long as you spend in worry over sons, friends, upkeep and business, and over whatever else, over wealth, grain, pleasures and fame, over gains, however much time you give to these, it is enough if you fix that mind on Kṛṣṇa's two feet for two minutes. It is enough to think of God for two moments. The dreadful, mighty gate of Yama opens of itself, and they offer their welcome. Today we spend all the time it asks on what is useless, fleeting and impermanent, on the things of the world. Of that time, do we give even a moment, even a little, to God? It is enough to fix the mind on those two feet for a single moment. But they do not fix it. You take out a small Śiva liṅga and give it to them: “My boy! Do abhiṣeka to this,” you say, and doing it becomes hard. Yet they will wash and wash a buffalo and scrub it clean. To wash a buffalo and bathe it there is time, but to pour a spoon of water on a Śiva liṅga and bathe it there is no time. For them. It is not for want of time. Nor is the work very hard. Śraddhā is low. In what is worldly, śraddhā is high. In what is holy, śraddhā is low. It is because this śraddhā is missing that the knowledge that comes of enquiry is missing in us. ‘Śraddhāvān labhate jñānam’: only through śraddhā is Jñāna gained. That is why we must develop śraddhā in spiritual matters.
Students! Only when you yoke the spiritual outlook together with your studies and travel with the two side by side will your life reach its goal. Learning alone is not giving men Śānti and happiness. Only the spiritual outlook gives man lasting happiness and Śānti. Spirituality is not self-centred. Saying ‘May all the worlds be happy’, from those days to these we have lived our Hindu tradition.
