Repetition of God’s Name and meditation should never be measured by mere external standards; they are to be judged by their inner effects. If one sways between impatience and sloth, and always worries, “Why has it not come yet? Why is it still far away?” then it all bolis down to repeating the Name simply and doing meditation with an eye always on the fruit thereof. The single fruit of repetition of Divine Names and doing meditation is the conversion of our focus from outward to inward, that is, seeing the reality of Atmic bliss. For this transformation, one has to be always active and hopeful, regardless of the time taken and the difficulties encountered. One should not count the cost, the time, or the trouble, and await the descent of the Lord’s grace. This patient wait is itself part of tapas (the austerity of meditation). Sticking unfalteringly to the vow is the austerity.

The God-centred person has three qualities: Purity, Perseverance and Patience. - Baba
