There are many good examples in the lives of the great devotees of the Lord of those who became indifferent to the rituals of the Vedas simply by devotional service to the Lord. When a person factually understands Krsna and his relationship with Krsna, he naturally becomes completely indifferent to the rituals of fruitive activities, even though an experienced brahmana. Sri Madhavendra Puri, a great devotee and acarya in the line of the devotees, says:

The Vedic rites and rituals are imperative for neophytes: comprehending all kinds of prayer three times a day, taking a bath early in the morning, offering respects to the forefathers, etc. But, when one is fully in Krsna consciousness and is engaged in His transcendental loving service, one becomes indifferent to all these regulative principles because he has already attained perfection. If one can reach the platform of understanding by service to the Supreme Lord Krsna, he has no longer to execute different types of penances and sacrifices as recommended in revealed scriptures. And, similarly, if one has not understood that the purpose of the Vedas is to reach Krsna and simply engages in the rituals, etc., then he is uselessly wasting time in such engagements. Persons in Krsna consciousness transcend the limit of sabda-brahma, or the range of the Vedas and Upanisads.
