Sree Sree Guru Gaurangau Jayatah!
Srila Saraswati Goswami Thakur realised the gradually deteriorating moral state of the conditioned souls in the future, in this black age. Nowadays, the aspirants desirous of worshipping the Lord sincerely from the core of the heart will find difficulty in performing all devotional forms wholeheartedly, remaining in the house. Also, they are not capable of performing bhajan like the realised elevated souls, Shadgoswamis, as complete renouncers.
As such, for giving scope to the intending novice votaries, he started establishing Maths where they can get a congenial atmosphere to perform bhajan. These Maths are in the middle of complete asceticism on one side and uncongenial disturbed household conditions on the other. Srila Saraswati Goswami Thakur, knowing fully about the aspirant's defects and inability to control sense organs, allows him to be admitted into the Math for starting bhajan, only seeing his slight inclination for worship of the Lord. The novice will find a completely better atmosphere in the Math and congeniality to do all forms of devotion as per scriptural injunctions. Of course, enhancement in bhajan will depend on one's sincere intensity.
