Vedic Siksha

As stated in Srimad Bhagwad Gita chapter 2.40 by Lord Krishna to Arjuna the importance of little devotion, how can it save us from a great danger.  नेहाभिक्रमनाशोऽस्ति प्रत्यवायो न विद्यते । स्वल्पमप्यस्य धर्मस्य त्रायते महतो भयात् ॥ 2.40 ॥ In this endeavor there is no loss or diminution, and a little advancement on this path can protect one from the most dangerous type of fear. We are not even aware of how powerful this is devotion towards Lord Krishna although if we do it nicely or not but it gives us the result as much as we do. But in material activities until and unless we do not reach at the end of the task we would not get the result out of it. That is why in devotion we can live a happy & peaceful life in present as well in next life too. How it save us in this life? We see there are so many faults in this age of Kali everywhere there are fights, quarrel, anxiety, tension, greed, lust and so many bad things are there and how can one live peacefully in this surroundings?...
