SB 4.21.37 P Instructions by Maharaja Prthu
While describing the system of protection for the creeper of devotional service, Sri Caitanya Mahaprabhu has especially stressed protection from offenses unto the
lotus feet of Vaisnavas. Such offenses are called vaisnava-aparadha. Aparadha means "offense." If one commits vaisnava-aparadhas, all of his progress in devotional service will be checked. Even though one is very much advanced in devotional service, if he commits offenses at the feet of a Vaisnava, his advancement is all spoiled. In the sastras it is found that a very great yogi, Durvasa Muni, committed a vaisnava-aparadha and thus for one full year had to travel all over the universe, even to Vaikunthaloka, to defend himself from the offense. At last, even when he approached the Supreme Personality of Godhead in Vaikuntha, he was refused protection. Therefore one should be very careful about committing offenses at the feet of a Vaisnava. The most grievous type of vaisnava-aparadha is called gurv-aparadha, which refers to offenses at the lotus feet of the spiritual master.

It appears from the talks of Lord Caitanya that a person who cannot keep his faith in the words of the spiritual master and who acts independently cannot attain the desired success in chanting Hare Krsna. In the Vedic literatures it is stated that the import of all transcendental literature is revealed to one who has unflinching faith
in the Supreme Lord and his spiritual master. Lord Caitanya firmly believed in the statements of His spiritual master, and He never neglected the instructions of His spiritual master by stopping His sankirtana movement. Thus the transcendental potency of the holy name encouraged Him more and more in chanting Hare Krsna, the maha-mantra.
Adi 7.74 Lord Caitanya in Five Features
A name that represents an object of this material world may be subjected to arguments and experimental knowledge, but in the absolute world a name and its owner, the fame and the famous, are identical, and similarly the qualities, pastimes and everything else pertaining to the Absolute are also absolute. Although Mayavadis profess monism, they differentiate between the holy name of the Supreme Lord and the Lord Himself. For this offense of namaparadha they gradually glide down from their exalted position of brahma-jnana, as confirmed in
Srimad-Bhagavatam (10.2.32):
aruhya krcchrena param padam tatah
patanty adho 'nadrta-yusmad-anghrayah
Although by severe austerities they rise to the exalted position of brahma-jnana, they nevertheless fall down due to imperfect knowledge of the Absolute Truth. Although they profess to understand the Vedic mantra sarvam khalv idam brahma (Chandogya Upanisad 3.14.1), which means "Everything is brahman," they are unable to understand that the holy name is also brahman. If they regularly chant the maha-mantra, however, they can be relieved from this misconception. Unless one
properly takes shelter of the holy name, he cannot be relieved from the offensive stage in chanting the holy name.
Adi 7.84 Lord Caitanya in Five Features
While chanting the holy name of the Lord, one should not desire the material advancements represented by economic development, religiosity, sense gratification and ultimately liberation from the material world. As stated by Caitanya Mahaprabhu, the highest perfection in life is to develop one's love for Krsna (prema pum-artho mahan sri-caitanya-mahaprabhor matam idam). When we compare love of Godhead with religiosity, economic development, sense gratification and liberation, we can understand that these achievements may be desirable objectives for bubhuksus, or those who desire to enjoy this material world, and mumuksus, or those who desire liberation from it, but they are very insignificant in the eyes of a pure devotee who has developed bhava, the preliminary stage of love of Godhead.
