One time, Andal, the mother of Bhattar, spent Vaikunta Ekadasi day by fasting the whole day. The next day, to complete the fast, she asked Bhattar to give her the Lord's divine water.

Bhattar replied "How did you manage to pick out the Ekadasi day from inside the great divine event (periya thirunAL)?"

That is, Bhattar is wondering how in the great event of Adhyayana Utsavam, that occurs over twenty days, and is meant to be spent entirely in bhagavad anubhavam, someone found the time to perform ekAdasi vratham. Bhattar's thought is that either one should not have even been aware that such a day was occuring or one should not have worried about following the ritual. That is, nothing should come between the devotees and bhagavad anubhavam during that time.
