By rendering devotional service unto the Personality of Godhead, Sri Krishna, one immediately acquires causeless knowledge and detachment from the world. — Srimad Bhagavatam, 01.02.07.
To attain freedom from material life, one must take to Krishna consciousness.
Srimad Bhagavatam 6.5.16,
The sankirtana devotees are very very dear to Krishna. Because you are doing the field work of book distribution, Krishna has immediately recognised them as true servants. Just like during war time, a farm boy or ordinary clerk who goes to fight for this country on the front immediately becomes a national hero for his sincere effort. So Krishna immediately recognises a preacher of Krishna consciousness who takes all risks t deliver his message.
God has created everything transcendental. It is simply our failure to see the ralation of everything with Krishna that makes every thing material.
