beyond birth and death chapter 2

we are all connected to the Supreme Lord, but now we have been affected by material contamination. The process is that we have to return to the spiritual world, and that process of linking up is called yoga. Another meaning of the word yoga is “plus.” At the present moment we are minus God, or minus the Supreme. When we add Kṛṣṇa – or God – to our lives, this human form of life becomes perfect.

The yogī knows all these descriptions, and he can transfer himself to any planet he likes without the help of spaceships. Space travel by mechanical means is not the accepted process for elevation to other planets.
