The Sages, Rishis, Munis and Mahans have been people of foresight. With boundless compassion, they have pitied about our plight, long back --
प्रायेणाल्पायुषः सभ्य कलावस्मिन्युगे जनाः ।
मन्दाः सुमन्द-मतयो मन्द-भाग्या ह्य् उपद्रुताः॥
(Srimad Bhagavatham 1:1:10)

In Kali Yuga, man will possess shorter lifespan, qualities of laziness, weak mind and easily susceptible to negative qualities and ills.
Thus, the modern day man needs an easier path -- something that can be accommodated in his busy life. That path should be such, that it does not involve a lot of rules and restrictions. it should not have time-bound restrictions; it should not involve much expenditure; it should be something which can be easily followed – In short, it should be perfectly relevant in the current day context, and absolutely practical; and yet yield us to the same goal.
ध्यायन् कृते यजन् यज्ञैः त्रेतायां द्वापरे अर्चयन् ।
यदाप्नोति तदाप्नोति कलौ सङ्कीर्त्य केशवम्॥

That supreme good which could be attained by the performance of meditation in the Age of Kruta, sacrifices in the Age of Treta and worship of the Lord in the Age of Dwapara can verily be attained, in the Age of Kali, by the mere chanting of the Divine Names of the Lord!
