Srimate Ramanujaye Namaha,

This is a very deep question and it is true that we do this mistake quite often.

It happens when we  forget who is the main doer of (good-satvik) action and also when we forget the mercy (given in the form of knowledge/skills)  given to us by Acharya /Guru.

Ideally we are supposed to be a bridge in passing off the praises to Guru and Krishna.. but when some thing gets stuck in the bridge  then we will experience what you have stated above..

But why does something sticks in the bridge is a complex question and will have multiple reasons not sure of the exact reason.

May be the elateness you are feeling is the happiness that your Guru/Acharya’s teaching/training is being praised.. So dont worry too much :)-

is it because of Samsara Vasanai or something else ??

Its due to split second ahankaram, mamakaram plus prakruthi karma or ruchi from vishaya sukham , not accepting that we are not kartha As Sri Acharya swamy usually says thanga vilangu punya , irumbu vilangu papa, it happens to the best of us Swami that’s the common defect of samsara.
