Bhava-grahi janardanah: “Janardana, Krsna, He accepts the feeling.” So we have to purify our feelings. That is Krsna consciousness: “How I can serve?” And if we purify… Purify means purification will be done by Him. We cannot purify. Purification will be done by Him. Simply we have to become purified feelings, that “I must serve Krsna very nicely.” Then He will give facilities, He will give you intelligence, He will give you everything.
