According to the first letter Lenin is fearful of a party congress. why and how does increasing the number of delegates to the congress help?

In his first letter, Lenin expresses concern that a party congress dominated by a small, unrepresentative group might lead to decisions that do not reflect the broader party's interests. By increasing the number of delegates, Lenin aims to ensure a more diverse representation of the party's various factions and perspectives, which would help mitigate the influence of any single group. This broader participation is intended to foster a more democratic and unified decision-making process, ultimately strengthening the party's cohesion and effectiveness.
