Why is that among the nine process of Bhakti, kīrtanam is the most easiest in kali yuga?

Kirtan is a call and response of sanskrit chants or mantras.

It’s typically done to a guitar, with a drum maybe, and often a harmonium.

Songs are simple - just one or two lines repeated over, and over, and over.

And in the repeating of these unfamiliar words which feel like aerobics for the mouth something truly magical happens.

When several people join together and practise Sankirtan, a huge spiritual current or Mahasakti is generated.

This purifies the heart of the aspirants and elevates them to the sublime heights of divine ecstasy or Samadhi.

The powerful vibrations are carried to distant places.

They bring elevation of mind, solace, strength to all people and work as a harbinger of peace, harmony and concord.

They annihilate hostile forces and quickly bring peace and bliss to the whole world.

In the end times, mental concentration is at it's all time lowest, true faith ceases to exist, and the most simplest yogas, though it may take millions of Kalpas to come to fruition, are the only ones these beings can comprehend. The Kama Sutra and Tantric paths, because they involve sexual bliss, are widely known, but not for the right reasons.

(Dude, Buddhism is about the only religion the people of the west understand, I know what Bhakti is and Kali Yuga, the last of the 4 Yugas, the dark ages, but for the most, people in the west are totally ignorant of your Sanskrit based words.)

Does it matter why it's the easiest? Just enjoy how easy it is. It was written that way, and people found it to be easy. Ok?
