Bogar states that before composing his own work, he studied a vast body of writing attributed to the great Siddhars who came before him — nearly 700,000 verses in total — condensing their essence into the 7,000 verses of Bogar 7000. The tradition names several of these sources directly.

In verses 1982–1983, Bogar groups the literature he consulted into fields, to make sure his own 7,000 verses touched every part of Siddha science and human life:
In the closing verses (1996–2000), Bogar describes his own process: he looked at works totalling nearly 700,000 verses (7 lakhs) and distilled their essence into the 7,000 verses of this text. He mentions travelling to China (Cheena Pathi) to witness its sciences and alchemy, and incorporating that knowledge into the work. He states he wrote in plain Tamil so that ordinary people would not need to wander in search of these teachings (Verse 1997), and credits his guru, Kalangi Nathar, for the grace to complete the task. In Verse 1980, he cautions that those who find fault with the work without understanding the depth of the research behind it do so at their own peril.
