Japa- yagna may not be appropriate for everyone. People are different with different Prakruti. Their nature is also different. In general this is all right. Whoever likes and wants to do Prabhu-Smaran it is alright. They afterwards felt that not everyone can do Prabhu-Smaran. So they suggested for others to do prayers - "ask whatever you want". When a child asks the mother whatever he wants, if mother is in good mood, only then she will fulfill the need of the child. Bhagwan does not have such issues between Him and us. So they suggested to do Prayers. First they suggested to do prayers and ask for physical things and ask for whatever you need or want. It is possible that our demands may not be fulfilled. Even in Sansar the demands are not always fulfilled by mother but that does not prevent the child from asking repeatedly. Prey to Bhagwan and ask from Bhagwan in similar manner. This is one way. They also showed other tools like Bhajan- Kirtan (singing the praise of Bhagwan), association with good and holy people, performing good deeds, letting go of things etc., and suggested to practice one or two tools that suites the nature. They also suggested to practice with tool that is higher than Prakruti, to go higher than Prakruti, but at the very moment, you must have the awareness of the purpose of using such tool and what is going to be accomplished by using such tool. While using the tool, this awareness must be living and propelling us towards Chetna (consciousness).
