Just as curiosity drives scientific progress, spiritual ignorance compels us to ask: Who created this vast universe, and why are we here?
Science explores creation; spirituality identifies the Creator — Supreme God Kabir Sahib, who resides in Satlok, the eternal realm beyond the reach of technology or space travel. While science treats diseases and enhances comfort, it cannot free the soul from the cycle of birth and death. Only through Naam Diksha (spiritual initiation) from a Tatvadarshi Sant, like Sant Rampal Ji Maharaj, can one attain salvation.
Even discoveries like DNA and quantum mechanics hint at a deeper design — not random, but divinely governed. The future of humanity lies not only in AI, space exploration, or genetic engineering but in recognizing that the ultimate truth lies in Satbhakti, the true worship of God, as guided in holy scriptures.
Science answers how, but only true spiritual knowledge reveals why.
