You know 'what exists' through science - 'physical energy'.
'what exists' through??
Pleasures are part of life, if they do not go against 'dharma'.
'Dharma' as society understands it. Cannot manufacture my own special 'dharma'.
Though I am 80, I have to care for my wife. She was feeling a little low today. I can't leave her in her old age after being together for >55 years.
Taking care of grandchildren if required by children is a 'dharma'.
We should be practical in Vyavaharika.
Oh..... Everyone has a secured ideal for what one does, but God knows whether the ideal is 'right' and 'rightly understood'. Irresponsibility of Parents to Children's (Father earning more more more money, and sending their wife to earn more more more instead of taking care of homely affairs) is never a dharma of the Grandparents, I feel. More money does not equals to responsibility, however security it might give.
If wife does not feel well, leaving her to take care by son would be better I feel (Dharma might not offend this I feel). Maybe time knows??
