You believe Avatars are incarnation of God and you worship them as such but the following is the counsel of Sikhi: ਅਵਤਾਰ ਨ ਜਾਨਹਿ ਅੰਤੁ ॥ ਪਰਮੇਸਰੁ ਪਾਰਬ੍ਰਹਮ ਬੇਅੰਤੁ ॥1॥ Incarnated beings do not know His limit. The Transcendent Lord, the Supreme Lord God, is infinite. ||1|| (Guru Granth Sahib Ji, Ang 894) ਜੁਗਹ ਜੁਗਹ ਕੇ ਰਾਜੇ ਕੀਏ ਗਾਵਹਿ ਕਰਿ ਅਵਤਾਰੀ ॥ ਤਿਨ ਭੀ ਅੰਤੁ ਨ ਪਾਇਆ ਤਾ ਕਾ ਕਿਆ ਕਰਿ ਆਖਿ ਵੀਚਾਰੀ ॥7॥ In each and every age, He creates the kings, who are sung of as His Incarnations. Even they have not found His limits; what can I speak of and contemplate? ||7|| (Guru Granth Sahib Ji, Ang 422) ਰਾਮੁ ਗਇਓ ਰਾਵਨੁ ਗਇਓ ॥
