Find the HCF or LCM of all living beings and see them from that level.
The HCF is the 'Highest Common Factor' that we have all learnt in maths - except that it is in spirituality. It is the commmon factor of that Brahman or Truth that is the basic substratum from which the pancha-bhootas (five base elements - space, air, fire, water, earth) have been formed and these form the basic constructs (panchikaranam) of all seen and unseen things in this universe. Through mananam (contemplation) and nidhidhyasanam (meditation), if you can find that common factor, stick onto it. You will be able to understand the oneness among all things this universe -sentient or insentient.
Similarly, the LCM is the 'Least Common Multiple' - the ultimate destination where all in this universe is heading into. It is the Nirvana or Moksha from cycle of births and deaths and merging into the that Unique Supreme Power (USP) called Brahman. THis is the final destination of everything in this universe - whether they strive for it or not. So consider all in that view point and you will again find the oneness in all.
Hari Om.
