In Jainism, particularly among the Śvetāmbara Mūrti-pūjaka tradition, the term "Gachhadhipati" refers to the head or leader of a Gaccha (sect or sub-sect). The "Labdhi Vikram Samuday" is a relatively new group within the Śvetāmbara tradition, primarily followed by laypeople and inspired by certain spiritual leaders.

As of my latest knowledge, the prominent spiritual leader associated with the Labdhi Vikram Samuday is Gachhadhipati Shree Labdhi Prabhuji (also known as Labdhi Vijayji Maharaj Saheb). He is revered as the guiding force and spiritual head (Gachhadhipati) of this samuday (community). His teachings focus on practical spirituality and the core principles of Jainism, emphasizing non-violence (ahimsa), truth (satya), and self-discipline (samyama).

If you are seeking the most current or specific name of the Gachhadhipati, it is advisable to refer to the official communications or website of the Labdhi Vikram Samuday, as such positions can change over time.
