Usually, all living entities have affection for some other living entities. Many living entities also have attachments to things.
If a human does not have other humans to associate with, or if they find those relationships unfulfilling, they often keep a dog or a cat or even fish or a lizard or something else.
Why do we love other living entities? Why are we attached to things?
instead of loving
a dog or a cat
why not love Krishna
who made all thatHis Holiness Vishnujana Swami (quoted by His Grace Sriman Sankarshan Das Adhikari
Everything everyone likes is originally enabled by God. Everyone you love is being personally emanated by God.
Whether its your most precious possession, or your most treasured relationship, there is one source.
Simply recognizing God as the source of every single experience that gives you pleasure is the easiest way to develop love for God.
My spiritual master gives the example of a generous roommate, who keep the fridge full with all kinds of most delicious foods and you are free to use anything you like without any payment in return! What do we pay for the sunlight, the air, the water, the earth, and the life that enables to enjoy it all?
We love or are attached to anyone or anything only because Krishna is manifesting them. Actually our love is for Krishna.
अहं सर्वस्य प्रभवो मत्त: सर्वं प्रवर्तते ।
इति मत्वा भजन्ते मां बुधा भावसमन्विता: ॥ ८ ॥
ahaṁ sarvasya prabhavo
mattaḥ sarvaṁ pravartate
iti matvā bhajante māṁ
I am the source of all spiritual and material worlds. Everything emanates from Me. The wise who perfectly know this engage in My devotional service and worship Me with all their hearts.https://vedabase.io/en/library/bg/10/8/
If we recognize this, we will be fully satisfied, fully content, and blissful always.
