So please try to sit for meditation and chant on gayatri mantra, by hook and crook.You can go to garden early in the morning to chant and meditate there.But see this money thus is only to maintain body and will be burnt at last.If we do not use this body to realise God then we have failed and will ever face sorrows, problems etc.
So to maintain the body we earn and must earn to wear clothes, to eat food, to live in house etc., etc.
However, to chant the mantra mentally is more powerful and you may chant mentally even while walking or in lying position.
In the evening, we are at work and could not be possible to chant.
Only the best time for me is in the afternoon between 1.30pm to 4.00pm (these are our lunch hours). However, I continue to do chanting mentally, whenever the time permits.
Soul thus does not eat, does want home, clothes etc., soul is away from all these requirements because all worldly requirements are meant for only body.
Soul is hungry only to listen pious preach about God.
